- change prototype of async proc calls to typedef int (*DoProcProc)(void *param); i.e., have the proc return a result. Turned out that almost all uses of the primop ended up encoding a result via their 'param'. - when adding new I/O requests, shorten the time the IOManager lock is held. Helps to keep down the size of the thread pool.
