That is the only way to background a process from within a loop.

I might have written something in expect, but usually I have more problems
with blocking pipes that way.

I played with it some more last night.  If the ddr1394 works the first
time, the script runs fine.  If it starts looping - killing the previous
ddr1394 and retrying, ddr1394 fails after the 3rd retry with a segmentation
fault!  I think I'm missing something about bash job control...
