	(S_proc_execdata_notify): Check return of malloc.
	(S_proc_register_version): Likewise.
	(initialize_version_info): Add asserts.
	* info.c (S_proc_pid2task): Do not bother searching for the pid
	if we do not have a valid caller.
	(S_proc_pid2proc): Likewise.
	Use memcpy, not bcopy.
	(S_proc_getprocinfo): Doc fixes.  Use MAP_FAILED not -1.  Use
	memcpy, not bcopy.

	correctly.
	(S_proc_setlogin): Check return value of malloc.
	* main.c (main): Assert allocate_proc.

	* pgrp.c: Include assert.h.
	(new_pgrp): Check return value of malloc and fail accordingly.
	(new_session): Likewise.
	(boot_setsid): Assert sess.
	(S_proc_getsessionpids): Use MAP_FAILED not -1.
