Subject: Allow retry to take arguments?

Hi all,

What would folks think of allowing retry to take two arguments - a
num_retries and delay argument.  Then you could do something like this:

begin
   connect_to_something
rescue Exception
   # Retry up to 3 times, sleeping 30 seconds between attempts
   retry(3, 30)
   raise
end

This would mostly be a convenience for db/network code, though I'm not
sure what other clever uses one might come up for it.

Good idea?  Fraught with danger?  Too difficult to implement?  Too
specialized?
