So perusing the aio code in preparation to disassocate it from the Squid
fs code, I found that there's a pipe being used as a notification/wakeup
mechanism.
Basically, thread completion writes a ! into the pipe; this wakes up the
main squid loop and calls a PF callback.
All the callback does is

Henrik,
Whats incomplete about the Variant invalidation support in PURGE/CLR in
Squid-2.HEAD?
There are many common corner cases where the existing vary_id isn't
picked up properly. The worst being if an object goes from not having

How could I configure squid to buffer whole POST-request before sending
it to peer cache or originserver?
Good question. It isn't really designed to do this. POST request may be
almost unbounded in size, and some streaming over HTTP

Subject says it all - open, read and unlink are async, but write and close
aren't.
Why is at least write not async?
Simply because when testing on Linux they very rarely block, with the fs
buffers absorbing them fully as long as you don't

Yeah, I'm testing async write at the moment. But I'm not exactly testing

Just for the sake of consistency and preference for better
troubleshooting and testing, are there any CFLAGS that I should be using
during configure and compile of Squid 3HEAD? I was using the same
options I was using with 2.6, which were:
CFLAGS=-DNUMTHREADS=65 -march=nocona -03 -pipe
Argh!
Please start putting relevant details into:
http://wiki.squid-cache.org/Features/VaryProcessing
That way we can have a proper list of whats required.
