I didn't explicitly send a PR on this issue.  There are a number of open
PR's (i386/5698, kern/6099) covering LPIP problems.  I don't recall seeing
any reply either.

I haven't done any further work.  I have done a bit of thinking about
how to go about handling contention, but didn't come to any firm
conclusions.  I only have one ECP machine, so I can't use an ECP
protocol in any case.  My only comment is that it would be useful if
the protocol could also be used on a normal bi-directional parallel
port.
