Very slow sed...

[David Cross]

Thanks all.. it was the memory.  It wasn't "bad".. .memtest (or anythign 
else didn't actually fail, the only way I could tell is with a stopwatch 
and watching loop times)... but pulling 1/2 of the RAM fixed it.. it 
doesn't matter which set was in, as long as both sets its fine.
