The t/data files are fine.

Also the largest file (full_2_psi1.xml) from release 2006-09-19 of the
MINT [1] database does not produce the crash.  It has a new warning, however:

   Can't call method "text" on an undefined value at
   /usr/local/share/perl/5.8.8/Bio/Network/IO/psi.pm line 290.

"ps ux" tells me VSZ = 272788 and RSZ = 254992. This is on x86-64 with
64 bit perl.  The box has 2 GB of physical memory so these numbers
don't seem to be a concern.

Do'h! You have the list address loud and clear in three places, but I got
your contact info from the AUTHORS.  Will use the proper channel from now

If we wish to count lines of code, we should not regard them as lines
produced but as lines spent.                       -- Edsger Dijkstra
