firebird-mirror/src/jrd/pag_proto.h
dimitr dc7aad88ed 1) Slightly refactored recheduling and checkout logic.
2) Re-enabled checkouts in PIO routines, this resolves CORE-4179. Windows build may be broken, please validate.
3) Implemented faster reaction on asynchronous cancellation/shutdown requests.
4) Avoided locking dbb_sync in AST. This change also solves races during massive attachment shutdown.
