[c-nsp] UDLD - why is default 60 seconds?

Why is the default probe message time 60 seconds and in addition one can
only go as low as 7 seconds?  If a GE port suddenly becomes
unidirectional, I would like to know about in 1-2 seconds and not after 7
seconds, so that the link is forced down and OSPF turns to an alternate
path.  Or am I missing something?

Thanks,
Hank
