that seems to be the general consensus.

given that CDS didn't exactly take off in a particularly big
way, it's not really justifiable.

hmmm.

consensus seems to be... nope! :)

byte range locking.

did you know that samba emulates byte range locking on top
of posix locks?

what they do is:

1) always make the posix locks r/w (_just_ in case...)

2) maintain a dual list of the 'emulated' byte range locks
and the 'real' posix locks.

the reason for having the posix locks always r/w is
because the byte range locks can potentially a) overlap
(yuck!) b) be read _or_ write.  and posix locks _cannot_
overlap.

anyway, thought that might be useful, if by byte range
locks you mean 'NT-style-semantics', which implies
basically that the range locks are allowed to overlap.

all best,
