What's the danger (if any) in setting cycbuffupdate to a really big #?

[Jaye Mathisen]

I'm assuming that if the system crashed, it may be an issue, but
barring having to slam back and forth from the beginning of a disk to 
the end when you're updating a big CNFS buffer near the end, why wouldn't
I want to bump that to say, a few thousand, rather than 25?  If I don't
care if I lose a few articles in a crash?
