[lug] kernel to user space transactions

[Jeffrey Siegal]

With all due respect, I think you're making too big a deal about copying
data.  100 mb/sec is only 10 megabytes/sec, and current system should
have no trouble copying that amount of data, as long as you don't copy
it too many times.

Mapping the incoming data from a kernel driver is fine, but once you're
doing with it, just write it out using a normal system call and be done
with it.
