Re: On resending a message

Check JCTools, Nitsan has been extending them with blocking implementation
during the New Year's holiday. May still be in review.

I hope this helps

On resending a message

['Alexandru Nedelcu' via mechanical-sympathy]

Hi,

On Nov 20 I've sent a message titled:
"_Queue that puts consumers to sleep?_"

I never got any replies and now that I look into Google Groups's online 
interface, I'm not seeing it anymore.


Given that I've been switching my Google accounts and thus my 
subscriptions, the message might have been blocked or the account never 
approved. This message I'm writing now might have the same problem.


Should I resend that message?

Re: Avoid stepping on page faults while writing to MappedByteBuffer

[Gil Tene]

mincore is no more useful than pretouch. Unless you lock, a page that was 
resident at the time of the mincore/pretouch operation can be evicted a few 
microseconds later. A “this seems to be resident right now” quality does not 
prevent page faults or long TTSPs and STW pauses on mapped buffer access, it 
just improves the stats a bit.

I think what you want is something like the mincore system call on Linux so 
your thread can write directly if the page is mapped but offload the work to 
another thread if it is not mapped. I don't have any experience with the system 
call though.
