[Peter Wang <tjaden@xxxxxxxxxx>]

Also attached is a fix for a bug that theoretically could crop up in
the OSS driver.  This might be related to the problem Vincent had
with the datafile loading failing (EINTR).

To get something done, a committee should consist of no more than three
persons, two of them absent. (or someone who's finished his mid-years :)
