I've seen this with 1.4 on linux [native-threads]. I think it is because
we are not queuing real time signals. Try killing your process with SIGRT0
or SIGRT1 [the numbers of the signals that the solaris emulation expects
for these] and see if you can get it going again. I believe RT0 is used
to suspend, and RT1 is used to resume, but I may have gotten them backwards.
