Subject: Error while uninterruptable causes MP 9318

Lisp Version: 10-Jun-84 18':41':09

Description: The following code causes a DLion to hang with 9318 in the MP':  (RESETLST (RESETSAVE (INTERRUPTABLE NIL)) (RESETSAVE (SUSPEND.PROCESS ''MOUSE) (WAKE.PROCESS ''MOUSE))).  Note that this code is erroneous (the second arg to the second RESETSAVE should be quoted), but crashing seems to be a bit severe of a punishment.'

I changed the subject to "Error while uninterruptable causes MP 9318" and declined it.  It''s a feature, sort of.  Basically, if you''re going to be so radical as to turn interrupts off, and then cause an error, you should not expect Lisp to treat it normally -- you said you wanted to be uninterruptable, yet at the same time you want to be able to service a normal break!'
'
In your particular case, had you continued the 9318 with a ^N, you''d have seen your error was ATTEMPT TO SET NIL OR T because of your incorrect RESETSAVE.  But any kind of error while uninterruptable would have given you the 9318.'

   The behavior is reasonable, but undocumented.  How about adding something about this under the RESETLST documentation (though I might be the only one around silly enough to make such a stupid mistake)?'
