I changed the 30 *.pp to 100 *.pp, but that makes it even harder to
trigger the problem:

$ ./u.sh > freezeU.out
./u.sh: line 6:  2796 Segmentation fault      (core dumped) make -j -f
MakefileU
Failed after 415 runs

*20040225 snapshot*

The 20040225 makes it easier again, with 30 *.pp and uname in
the Makefile I got:

$ time ./v.sh > freezeV.out
make: *** wait: Interrupted system call.  Stop.
make: *** Waiting for unfinished jobs....
Failed after 216 runs
