will you make 1:1 threading working ? I just posted a patch to Jeffrey and Matt, this change creates lots conflict with my patch. :-)

oh sorry, i didn't know you were also working on that. maybe we both should utilize the mailing lists more :)

my plan was to slowly adjust the code to use lwps where appropriate, and when that's done, add code for signal/fork/exec/exit. i'd like to have 1:1 working in the december release.

what are your plans? i'm happy to review patches!


I just picked up an early patch. I have removed p_lwp and replaced it with dynamically allocation, but it still can only support one lwp per-proc, another change is that I use lwp_sigmask and some signal code is now per-lwp based, for example sigprocmask(). I will send the patch to you in another mail.
