When a thread blocks on I/O, it _really_ blocks -- no other threads will be scheduled within that [rfork_thread'd/cloned] process. Other PTHREAD_SCOPE_SYSTEM [rfork_thread] threads will continue to run. I haven't decided yet whether to allow PTHREAD_SCOPE_PROCESS threads (which would run within the main process, and when one of them blocks the main process blocks), or to silently treat process scope threads as system scope threads. > > Unfortunately I don't have the time to help the Java porting > > effort, but I would like to hear about any problems the porters > > are having with our current libc and any expected problems from > > a libpthread that will act very similar to linuxthreads. > > Will do...
