|Hold on, here, fellas.  Is there a real reason to flush the font?  This thread

|This isn't so that your customers feel that you've returned all your memory,

That's definitely THE main reason most third parties do the HUGE AllocMem,
as the last thing before closing shop.

|things if necessary to satisfy your requests.
|
|Problems I'm aware of include:
|1) Expunge should walk the device/libs lists in reverse order so that if one
|  library is opened by another, the opener hears the expunge first.
|  (discovered by Bill Hawes, the little genius).
|2) Expunging should terminate when it gets enough memory for the AllocMem.
|3) Some device (serial maybe) hangs onto resources until it is expunged, so
|  expunging it is  the only way to get the resources back (this would be a
|  bug in the device).

Are these bugs still present in 1.3?  In they are, why weren't fixes included
in SetPatch if, as it seems from your comments, these are all known bugs?

|If I'm missing something here, I'd be pleased to be educated.

No, you're not missing anything.  Bu from now on consider that, as I said, the 
practice is widespread.
