Re: spurious timeout on nth Apple event on Snow Leopard

Not if the delay is consistent -- the bug you're referring to only happens every 65,000th time.

I cannot confirm this. I get values far under and over 65000 - on subsequent runs. So I'm a bit skeptical about the "it's only a counter problem" assumption.

Config: Mac Pro, 10 GB RAM, OS 10.6.1
There's a problem #2: If you run the following script in AppleScript Editor it eats over 5 GB of RAM in about 20 minutes. I stopped there as the system became very sluggish. The first gigabytes are eaten quite fast, then it gets slower and slower.
So I ran it in Script Debugger where it took 3.5 minutes and far less RAM was eaten (220 MB):
-----
set L to ""
repeat 10 times
repeat with i from 1 to 500000
try
with timeout of 5 seconds
tell application "TextEdit" to current date
end timeout
on error errm number errn
--display dialog "timeout" & i & " " & errn
set L to (L & i & return)
exit repeat
end try
end repeat
end repeat
L

Whoops, now as expected. But I swear by 1000% that I have usually other values in Script Debugger... because I made this "find missing event" routine for one of my important scripts which I always run in Script Debugger.

Though, now I have something ;) When I strip the script a bit and run it repeatedly in AppleScript Editor (still eats RAM):
-----
set L to ""
repeat with i from 1 to 300000
try
with timeout of 5 seconds
tell application "TextEdit" to current date
end timeout
on error errm number errn
--display dialog "timeout" & i & " " & errn
set L to (L & i & return)
exit repeat
end try
end repeat
L

Should be always 65536, or a few counts under.
