I haven't looked at the code so these may be questions arising from

What native code in classlib requires special thread support and why?

Could we simply override those classes and eliminate this need, and
just remove (or ignore) the classlib thread stuff?

Why can't whatever code uses thread_attach() use the normal JNI methods
for thread management instead?

JCHEVM should be compatible with any native library that adheres to
the JNI spec.. but if it requires other "backdoor" functions to be
supplied by the JVM, then in theory we can eliminate that requirement,
because after all normal Classpath doesn't require it and it works
just fine.
