itself here, to avoid a race. (cygthread::release): Clear more stuff. Add a diagnostic for an internal error. * cygthread.h (auto_release): New function. * pinfo.h (pinfo::remember): Add an argument to denote whether child is detached. * fork.cc (fork_parent): Reflect change in arguments to pinfo::remember. * pinfo.cc (_pinfo::exit): Signal exit more forcibly. (proc_waiter): Use cygthread::auto_release to signify that cygthread::stub should release the thread. This should avoid a race. (pinfo::alert_parent): Don't signify an error when wr_proc_pipe == NULL. * sigproc.cc (proc_subproc): Add support for PROC_DETACHED_CHILD. * sigproc.h: Ditto. * spawn.cc (spawn_guts): Specify whether child is detached or not when calling pinfo::remember.
