Hiroshi Yokota [Sat, 6 Feb 2016 01:25:48 +0000 (10:25 +0900)]
Fix user-defined signals drop by marker threads

When one user thread sets its own signal handler in multi-threaded
code, GC marker thread sometimes steal and drop user signal calls.
Because GC marker thread doesn't knows the user thread's signal
handler, and uses the default signal handler that ignores any signal
call.  This becomes to drop the signal call.

GC system signals, and don't drop user signal calls.
