Its not currently possible. We have two services which effectively do this
by communicating with a back end user space program and keeping a cache of
results (mrouted for multicast routing, and arpd for ARP on very big switched

:-((. I would like to have much memory to work around a Windows 95 bug in
smbfs. Or, do you think it is possible to vmalloc about 64k temporarily
during a readdir call? I need it because I want to get a complete directory
