Greetings,
Robbin rebased the project last night/this morning to merge with Thread
Local Handshakes (TLH) and also picked up additional changesets up thru:

8191049: Add alternate version of pns() that is callable from within hotspot
source
Summary: added pns2() to debug.cpp
Reviewed-by: stuefe, gthornbr
This is the first time we've rebased the project to bits that are this
fresh (< 12 hours old at rebase time). We've done this because we think
we're done with this project and are in the final review-change-retest
cycle(s)... In other words, we're not planning on making any more major
changes for this project... :-)
*** Time for code reviewers to chime in on this thread! ***
Here is the updated full webrev:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-08-full/
Here's is the delta webrev from the 2017.11.10 rebase:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-08-delta/
Dan has submitted the bits for the usual Mach5 tier[1-5] testing
(and the new baseline also)...
We're expecting this round to be a little noisier than usual because
we did not rebase on a PIT snapshot so the new baseline has not been
through Jesper's usual care-and-feeding of integration_blockers, etc.
We welcome comments, suggestions and feedback.

Here is the updated full webrev:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-07-full/
Unlike the previous rebase, there were no changes required to the
open code to get the rebased bits to build so there is no delta
webrev.
These bits have been run through JPRT and I've submitted the usual
Mach5 tier[1-5] test run...
We welcome comments, suggestions and feedback.

I ran the above bits throught Mach5 tier[1-5] testing over the holiday
weekend. Didn't see any issues in a quick look. Going to take a closer
look today.

Greetings,
Resolving one of the code review comments (from both Stefan K and
Coleen)
on jdk10-04-full required quite a few changes so it is being done as a
standalone patch and corresponding webrevs:
Here's the mq comment for the change:
stefank, coleenp CR - refactor most JavaThreadIterator usage to use
JavaThreadIteratorWithHandle.

Greetings,
We have a (eXtra Large) fix for the following bug:
8167108 inconsistent handling of SR_lock can lead to crashes
https://bugs.openjdk.java.net/browse/JDK-8167108
This fix adds a Safe Memory Reclamation (SMR) mechanism based on
Hazard Pointers to manage JavaThread lifecycle.
Here's a PDF for the internal wiki that we've been using to describe
and track the work on this project:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/SMR_and_JavaThread_Lifecycle-JDK10-04.pdf
Dan has noticed that the indenting is wrong in some of the code quotes
in the PDF that are not present in the internal wiki. We don't have a
solution for that problem yet.
Here's the webrev for current JDK10 version of this fix:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-04-full
This fix has been run through many rounds of JPRT and Mach5 tier[2-5]
testing, additional stress testing on Dan's Solaris X64 server, and
additional testing on Erik and Robbin's machines.
We welcome comments, suggestions and feedback.
