Subject: [Mono.Posix] Workaround signal raising behavior.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?a=commitdiff_plain;h=0214d9669ab74cd2f77e53e031560c328b5efbd0;p=mono.git

[Mono.Posix] Workaround signal raising behavior.

The effects of Stdlib.raise() aren't immediate on OS X. The result is
that UnixSignalTest.TestDispose1():

	Stdlib.raise (Signum.SIGINT);
	Assert.AreEqual (a.Count, 1);

_may_ fail depending on timing.

Insert some Thread.Sleep()s to try to allow the signal to propogate.
