Two years ago, we ported the Sun JDK-1.1.6 on native LinuxThreads and
did *NOT* use SIGSTOP(because, if I remember correctly, this schema
was not sufficient to insure correct thread synchronization on
multiprocessors); at the same time, I implemented the very first
version of the LinuxThread support within GDB-4.17 to debug it,
and it worked !
