cycbuff limit?

[Pete Ashdown]

I'm building a big phat news server that currently has 286 2Gig cycbuffs
created.  INN 2.3 was dying silently until I found that it would only
accept 215 cycbuffs, anything higher would not work.

Is there a limit I can boost to get beyond this?  Also, the reason I'm
doing this is due to the maturity of raw disk access on Linux.  However,
its been a long time since I've messed with that.  Has it gotten better?
Is it more desirable than 286 2Gig files? :-)
