* cygheap.cc (cygheap_fixup_in_child): It's not just for exec.
* cygtls.h (struct _cygtls::thread_handle): New field. * dcrt0.cc (exit_lock): Remove declaration. * winsup.h (exit_lock): Add declaration. * exceptions.cc (sigpacket::process): Properly return after signal_exit. * pinfo.cc (pinfo::exit): Only exit the process if _my_tls.thread_handle has not been filled out -- which should be an impossible event. * sigproc.cc (sigproc_terminate): Fillout _my_tls.thread_handle to provide something for wait_sig to wait for. Use the siginfo_t version of sig_send and fill out the tls argument with _my_tls. (wait_sig): Wait for the thread specified in pack.tls or (for now) complain bitterly if it doesn't exit.
