When my Dad start a printing from his client my machine goes _down_. My
mouse stall completly and chars appear on the screen after msec of delay.
I am quite sure the overkill is the udelay().

Now I applyed this patch and recompiled and I'll see what will happens at
the next printing ;). I remeber we just discussed this issue some time
ago and at the end I agreed with you, but now that I become ill every time
there's a printing in progress I would like to reopen the issue ;).
For the record, I am using the last ieee1284 that Tim suggested me to use
some weeks ago.
