Subject: [PATCH] Examining the previous change I see that it will introduce a
 race condition when circuits are being created and destroyed at close to the
 same instant in time. See revision 11786 of cac.cpp which fixes mantis 334 if
 you are interested in what this code does. After running the regression
 tests, I pushed in a fix (which is removing above mentioned change and
 restoring the increment of iiuExistenceCount in cac::findOrCreateVirtCircuit.
