Attached is the output of running "perl -Mblib test.pl" in my Foo module
with PERLIO_DEBUG pointing to a file.
This time the test program dies with "refcnt_dec: fd 4: 0 <= 0"
(presumably debug.txt itself is now fd 3).
I'm not sure that it helps me very much.
I'm leaving now, but I'll have a closer look tomorrow (unless you've
sorted it all out by then ;-)
