but have no time to do them today and tomorrow -:(.
1. Add int waitMask to LOCK to speedup checking in LockResolveConflicts: if lock requested conflicts with lock
requestedby any waiter (and we haven't any lock on this object) -> sleep
2. Add int holdLock (or use prio) to PROC to let other know what locks we hold on object (described by PROC->waitLock)
while we're waiting for lock of PROC->token type on this object.
I assume that holdLock & token will let us properly and efficiently order waiters in LOCK->waitProcs queue (if we
don'thold any lock on object -> go after all waiters with holdLock > 0, etc etc etc).
Comments?
