At least in the unix ports of libgcj, Thread.interrupt sends a signal
to the target thread, the idea being that this will interrupt any
blocking I/O operation there.

This requirement (if it is one -- gcj goes its own way for the native
code and so I can't really speak for Classpath here) would be a great
addition to the VM integration documentation.
