In a message some time ago Brendan Eich mentioned that setTimeout caused a
"memory leak" -- as does eval -- because its string is not cleared, but
again this is heap related not stack related.

IAC... as you can see, 14K+ iterations shouldn't be too much of a problem
for most any script (the average manner makes just 120 iterations a minute,
the average cliock just 60).  If anyone leaves their browser on one URL for
that many iterations has got to be insane!
