interruptible. (call_handler): Avoid suspending a thread if it owns a mutex. Only set signal_arrived if the thread was actually interrupted. (events_init): Initialize module information needed by interruptible(). (sigdelayed): Don't call sig_dispatch_pending since it could screw up * init.cc (dll_entry): Record module handle of main for use by interruptible(). (proc_subproc): Reorganize handling of terminated child so that the bulk of the processing comes from the signal thread. (wait_sig): Force processing of waiting threads if SIGCHLD is not processed. * sync.cc (muto::release): Set tid == 0 after lock is released or signal processor will be confused.
