Actually I'll wager money you DON'T know where it came from because it's 
really obscure :-)

When I wrote the original SCSI code I wrote it for MACH and only later 
did I port it to 386BSD
from which it went to FreeBSD (and is still in NetBSD I believe).  I 
originally selected 15 seconds
because it was needed by an  AEG SCSI neural net based OCR/ICR character 
recognition engine
we used to use with MACH.

I set it to 3 seconds on my systems..
