Subject': Chat fatalities'
To': Vanmelle, Lispsupport'
'
The following sequence of events will cause you to fatally lose control of your sysout':  (On a dorado, don''t know about other machines)'
'
Before having gotten a chat window set up, do'
'
CHAT(PHYLUM)'
'
system prompts for a window region.  Don''t give it--instead, walk away for a half hour or so, with it still in the getregio prompt.'
'
Come back, and then give it the region.  The window will open, perhaps you will see some messages abot non-existent ports, and then you will be in a loop with all interrupts turned off, with the cursor periodically inverting for GC.  Mouse tracks, nothing else works.'
'
CTL-SHIFT-DEL may or maynot get you into Raid.  But in Raid, ^D gets you back to the same unresponsive loop.  Sysout is lost.'
'
Presumably, something gets out of sink when the connectio disappears because of some sort of time-out?'
