RE: Many Failures In libjava Testsuite!

["Boehm, Hans" <hans dot boehm at hp dot com>]

I didn't think the collector was built with -DUSE_COMPILER_TLS?
It probably should be.  But for now, tls support probably doesn't matter;
the collector uses its own implementation by default.

I added to the bug report.  I suspect the problem is with the collector's
interception of pthread_create calls, or lack thereof.
