	* exceptions.cc (_threadinfo::interrupt_now): Avoid double call to
	sigdelayed.
	* pinfo.cc (_pinfo::commune_send): Avoid inexplicable test which caused
	most pids to be shown as "<defunct>" on Win9x.

	* cygheap.h (init_cygheap): Play more vfork shell games and move
	ctty_on_hold and open_fhs_on_hold (back) here.
	* dcrt0.cc (_dll_crt0): Just set impure_ptr_ptr here and let later
	initialization deal with tls.
	* dtable.cc (dtable::vfork_child_fixup): Move ctty considerations here.
	(dtable:vfork_parent_restore): And here.
	* fork.cc (vfork): Reflect change to ctty handling.
	* perthread.h (vfork_save::fhctty): Eliminate.

	* cygwin.din: Make more exports NOSIGFE that will never be interrupted
	by a signal.

	* init.cc (dll_entry): Set stackptr to NULL to catch problems earlier.
