Please let me know what the problem was, even if it was just the 'global tas'
thing. I am trying to make sure this works on all platforms. Thanks.

I made this patch against 6.3.2 and ran regression successfully. This on a
glibc Linux x86 system. I just rebuilt against the latest CVS (from anoncvs)
and see 27 tests that fail, many with dropconns. I looked a little into the
'drop database failure' and it does not look related to spinlocks as far as
I looked.
