Thanks for the fix. It's incomplete, though. Previously, C-z would make the program print "resumed", then become insensitive the signals present in waitmask. With the 2012-08-16 snapshot, C-z stops the program, but on resumption, it doesn't print "resumed". Instead, on resumption, the program enters the same signal-insensitive state it did with the 2012-08-07 snapshot.
