One concern I had regarding relayfs, which was raised previously, was
regarding its use of vmap,
http://marc.theaimsgroup.com/?l=linux-kernel&m=110755199913216&w=2 On x86,
the vmap space is at a premium, and this space is reserved over the entire
lifetime of a 'channel'. Is the use of vmap really critical for
performance?

thanks,
