Sure, how about replacing the last line of the patch description with:
    Unfortunately, the loop doubles the time before sleeping, causing the
    initial sleep to be doubled.  This patch fixes the initial sleep time.

If this change is acceptable, do you want to make the change or should Nayna repost the patch?
