I was looking at some of the ULPs.  SDP sets the timeout to 20, without
explanation.  DAPL has a #define (set to 20 saying it is 4 sec in a
comment).  simple example?  Set to 20, no reason.  To me, it ends up
just being this opaque value.  Maybe some pre#defines in CM would make
it clearer.  Unfortunately, advertising milliseconds or jiffies will
just confuse consumers since the timeout cannot be that granular.
