Since you are on Unix, you can try STATUSLINE, available from my web
page.  It does exactly this sort of thing.

http://cow.physics.wisc.edu/~craigm/idl/idl.html    (under Misc)

If the output truly dominates the processing speed then of course you
could only output every 10th or 100th iteration.  You're still not
missing much if there are 10^6 iterations.
