> I've noticed table repeatable operations impacting other table ops. Upon looking at the
code it appears as though we reserve the name space, attempt to lock it, and then lock the
table. Someone more familiar with the code can debunk me, but it appears as though we're blocking
table ops on alternate tables. The same code for getting the lock is used for namespace and
tables, it seems as though in most cases we only want a table lock, we could change the path
to be ztable_lock/namespaceId/tableId.
