(Not that it would help me much if I were dead, I guess...)

Might some enterprising developer want to write a Macsbug dcmd that will
keep track of the state of a handle/resource?  It would trap _HLock,
_HUnlock, _HPurge, _HNoPurge, _AddResource, _DetachResource,
_ReleaseResource, and _DisposHandle, oh yeah and _HSetState too.  You
tell it to keep track of a certain handle, and to drop into Macsbug when
its state changes a certain way.

See, I have this resource, and the code goes through some incredible
gyrations to keep it locked when necessary and unlocked when not, and
it's screwing up somewhere between function X and function Y.  If I
could just break into Macsbug at X, find the resource, tell this dcmd to
keep its eye out for any calls that unlock it, and continue, I'd be home
free.  I've been trying to track it down, and after several hours and
thousands of lines of code (one at a time), I'm not any closer.

Does anything like this exist already?  Can it be done with a macro
(break on these a-traps, check the state byte, continue iff the locked
bit is set)?  Does anyone with lots of free time want to write it?
Or should I tack this onto my Things I'd Really Like To Write list?
