Certainly.  Attached.

Let me clarify.  Starting with the 2006-03-13 snapshot, every snapshot I
tried caused problems.  Although I did not try every one (sorry, but I
did not keep track of which ones), I know I tried over half of the 18
or so snapshots in question.  Since none that I tried worked, I have
been held at the 2006-03-09 snapshot.

The basic problem noted in each case had to do with forks - either a
cron script hangs (as reported), a build script fails because of fork
failures ('resource not available' type messages), or couldn't bring up
shell windows (as reported in

All of this started with Christopher Faylor's changes related to 'fork'
that started with the 2006-03-13 snapshot.  As I did report one problem
related to this matter on the 3/15 but go no response, I figured the
work was ongoing.  I just kept trying subsequent snapshots hoping the
problem would be cleared up eventually, but it hasn't.
