Detailed Description

Maintains the number of code paths on the current call stack that need protection from new debugs() calls. Squid cannot block re-entrant debugs() calls, but the high-level debugs() handling code queues re-entrant logging attempts when Busy() instead of letting them through to sensitive code.
