The compile process for jdk 1.6 just takes ages to compile and doesn't proceed to the next compile. Compile moves very very slowly atleast on my machine on amd64. Similar thing happens for mono, compile hangs.

We just need to fix the library. I don't have a machine to test for now, will have it in a few days. I will test your patch then, but if anybody has the time, please report back. > > Index: rthread_sched.c > =================================================================== > RCS file: /home/tedu/cvs/src/lib/librthread/rthread_sched.c,v > retrieving revision 1.10 > diff -u -p -r1.10 rthread_sched.c > --- rthread_sched.c 19 Feb 2012 02:07:48 -0000 1.10 > +++ rthread_sched.c 20 Feb 2012 20:06:15 -0000 > @@ -136,13 +136,8 @@ pthread_suspend_np(pthread_t thread) > > if (thread == pthread_self()) > return (EDEADLK); > - /* > - * XXX Avoid a bug in current signal handling by refusing to > - * suspend the main thread. > - */ > - if (thread != &_initial_thread) > - if (kill(thread->tid, SIGSTOP) == -1) > - errn = errno; > + if (kill(thread->tid, SIGSTOP) == -1) > + errn = errno; > return (errn); > } >
