I don't know if it's related, but we were running into a problem like this
on some IBM laptops because we were calling their SMI-invoking control
methods with the Global Lock held (by accident). Linux had a problem where
grabbing ANY mutex also grabbed the GL. Could it be the same issue?
Inserting a counter on While ops seems like a big kludge to me..
