I have a tree here where I added a (gc) call before and after the
port-for-each call in popen.scm (in the child).  Given that and
--with-threads=yes, "make check" would hang every time I ran it.

I rebuilt that tree with --with-threads=no and I ran make check
repeatedly.  After 20 iterations, it hadn't blocked.

So I removed the (gc) calls and rebuilt with --with-threads=yes, and
make check blocked after 7 iterations and then 183 iterations.

Though not conclusive, these results, when combined with the gdb
backtrace I posted earlier showing the blockage in scm_gc() while
trying to lock a a mutex, seem to suggest that the remaining problem
is thread related.
