I think this should default to 'false', because IMHO, this seems like an 
odd feature.  I'm not crazy about the fact that there's a Kconfig option 
for it either, but I'm not going to NACK this patch.

I personally would prefer to drop this patch, and just wait for 
full-blown pre-timeout support.  It feels like a debugging feature that 
doesn't really belong upstream.  But like I said, it's just my opinion, 
and I won't complain if I'm outvoted.
