[Wine] Parallel port access speed, cpu usage

Accessing the parallel port through wine is extremly inefficient:
I have heard of people with 2 Ghz CPUs were the speed of the
parallel port was still a lot slower than on windows. I have
tried on an old Pentium 233 MMX and an AMD K6-2+ 500. Parallel
port access is slow, CPU usage is at 100%. Parallel port
access speed scales with CPU speed.

I'm using the parallel port for an EPROM burner. EPROMs that
should be burned in seconds take minutes.
