Change 152332 by peter at peter_overcee on 2008/11/01 22:58:20

	AARGH!!!!
	Fix the value of SIG_SETMASK in sigprocmask syscall.  (It is 2 on linux,
	3 on FreeBSD.)  This was duplicated rather than using #includes.
	
	This is responsible for the assertion failures on non-trivial code due to
	signals getting unblocked when they should have remained blocked for the
	interpreter-driven periodic polling to find them.
