I believe mysql relies on SIGHUP or a fork to handle signals.  Mysql
may actually work now, but I haven't tried it.  I don't think the JDK
relies on signals other than synchronous signals which should work
OK with libkse.

I was more interested in the statement that "jdk is only guaranteed
to work with libc_r" that one of the Java developers posted.  I
took it to mean that the implementation of our jdk is geared
towards libc_r (perhaps knowing internal stuff about how libc_r
works).  I don't want anything like that to stop us, and we
can add some common APIs to the threads libraries if needed
to support it.

That should be good.
