How about:
1) Re-write the loop in C, perl or equivalent using setitimer().  You
   can system() out to collect the results.
2) <kludge>Write a small C program that uses setitimer() and signals
   its parent whenever the timer triggers.  Run it in the background
   and just pause within the sh loop.</kludge>
