That's exactly what I said. The basic system calls are defined
by Microsoft POSIX subsystem. Aside from that, you need architecture and
system-specific long jump procedures, among other things, and
ideally some tuned string and math procedures.

I don't agree.

There's no reason that signal(2) and raise(2) can't be
implemented in pure Java 7, aside from the usual syscall machinery.
They're usually implemented as system calls.
