2.2.18pre22: ppa_fail(3) from ppa_wait at line 319

With 2.2.18pre22 I get a lot of scsidisk I/O errors on my parallel port zip.

All pervious versions of 2.2.18pre worked fine. The problem is 100% reproducible and occurs
after a long period of inactivity (10 or more minutes)

compiled with #define PPA_DEBUG 1 I get:

ppa_fail(3) from ppa_wait at line 319

if you need more information please contact me directly as I am not on the list

the following partial reversal patch seems to help (but I am not sure it is correct):

            return 0;

Hmm. That patch went in because without it it doesn't work at all for some people. :-((
