- Yes, please. Post it. I mean, people are alluvthetime posting
- stuff on the net which is almost guaranteed to hose your system
- ("Oh, sure, I unplug and reconfigure my SCSI bus with the power on
- all the time, go ahead, do it"). This sounds like something useful
- with little chance of such hosery. Quick&Dirty instructions for
- using emacs to make the patch would be great fun. Or, grab the
- alphalock.c program and hack it to increase the buffers. Or, send
- the information to me and _I'll_ hack alphalock.c to do it :-).
