Unfortunately it is not easy for me to add pagecache support
to ncpfs, as couple of ncpfs users uses ncpfs in shared environment
with database record locking, and if I'll now read full 4KB instead of
128B record, it can clash with records locked by other clients.

I can for sure add `leases' like Novell Client for Windows does for
possibility of file caching, but I'm not sure whether size of code
needed for supporting this (and for supporting server driven
cache flushes) is worth of effort.

P.S.: And as NCP protocol is totally synchronous (even if it uses
TCP, I explicitly asked in Utah), only local file caching can increase
ncpfs performance, as there is no such thing like asynchronous file
