I looked through the code a bit.  I notice that _Jv_MutexLock enters
the critical section with each call.  But really, don't we only need
to do that once, since we're explicitly keeping the lock count?

It seems to me that this code could work along the lines of the POSIX
code.  And then in this case the above could be simplified; see
posix-threads.h and posix-threads.cc.
