[George Staikos]

SVN commit 474313 by staikos:

I just discovered this missing lock in kstvector.  This is a serious potential
for crash.  It affects 1.1.1 as well, but it needs testing first.  Should we
hold 1.1.1 or release 1.1.1 and do a very quick 1.1.2 with this fix and some
performance work?

I'll backport after testing is complete.
