System: NetBSD azenomei.falu.nl 1.4.1 NetBSD 1.4.1 (AZENOMEI) #27: Wed Jun 14 01:41:57 CEST 2000 rhialto@azenomei.falu.nl:/usr/src/sys/arch/alpha/compile/AZENOMEI alpha


>Description:
	
	I built a thread-aware python with unproven-pthreads.
	Subprocesses started to get SIGVTALRM signals.
>How-To-Repeat:
	
	Attempt to install Mojo Nation (see www.mojonation.net).
>Fix:

"config.h" is needed for HAVE_VFORK.
<sys/syscall.h> is needed for SYS___vfork14.

Maybe we should even wrap vfork() *and* __vfork14()?
