Re: BUG: restore_queue_signals(): q = 2 != queue_in = 3

[Bart Schaefer <schaefer@brasslantern.com>]

OK, this is one of those cases where I had to choose between HEAPDUP and
queue_signals() and I missed some "return" in the blocks.  There aren't
other globals being manipulated here so rather than try to catch all the
early "return" let's just drop use of PAT_STATIC.
