ps: the simple code is in, src/thread/PTHREAD/ThreadPThreadC.c, disabled subtley by inserting a 0, and the m3makefiles point at the usre threads. Probably I should debug it.

First attempt failed.
I didn't debug it.
Juno works now on OpenBSD/x86 with user threads in head.

I'm using the setjmp + poke around to set the stack/pc method.



Take a look at the sigaction technique mentioned in the paper.  I think it may be more reliable.


What happened with trying to use the thread stopping np primitives?



Later..

I think are ok.
I might run some more loops, but:
   - enter/leave critical section mixup fixed 
   - head-only regression fixed 
   - suspend/resume mismatch fixed 
Might cover it. (Every time I figure out a bug I think that must be the last one. :) )
OpenBSD is understood but not fixed. Their pthreads library is usermode and stinky. AND they don't have make/set/get/swapcontext.
OpenBSD probably won't make this release. I'm working on it in head but initial two attempts didn't work.



We can emulate make/set/get/swapcontext as per http://www.usenix.org/event/usenix2000/general/full_papers/engelschall/engelschall.pdf, using setjmp/longjmp/sigaction.
