Bugcheck 243 (missing pointer page) while preparing/executing statements that reference a table being dropped/recreated by another connection [CORE1938] #2377

Sometimes the DROP TABLE code is able to get the EX lock on the table while the relation block is still being used by other connections. This allows the "in use" table to be dropped, causing a bugcheck when attempting to access its data pages. The issue is visible in multi-threaded builds (Vulcan and FB v2.5) only, but I suspect prior versions are theoretically affected as well.
