This bug is *only* for cases where you press Run and nothing happense, but
no error message appears. It is a threading problem inside Runner.java.

*** The bug that brings an error message stating "Target VM failed to
initialize: VM initialization failed" is Bug #796, not this one. ***

*** This bug happens only intermittently. If no sketches run at all, you
have a different problem. ***

From the earlier, mangled bug report:

Major changes were introduced with the new run/debug setup in 0136, and one
of them causes sketches to not run every ~10th time or so (this will vary
depending on your machine). Hitting Run again should make things start up.

The problem has been tracked to the join() calls inside Runner.java,
however the exact problem is unclear.

This may be specific to Mac OS X, as I've only seen it on my G5. However,
since it's a threading problem, it's probably elsewhere too and I'm just
not seeing it yet.

*** Bug 775 has been marked as a duplicate of this bug. ***

Closing, this seems to be a phantom bug.
