Ah, ok.  In this case, I would suggest:

 - library in package named libfailmalloc0 and installed to

 - failmalloc program and bare /usr/lib/libfailmalloc.so symlink in a
   package named failmalloc.

Thanks, glad you like it. :)

That script cannot be included in the libfailmalloc0 package, since to
do so would prevent libfailmalloc0 and a future libfailmalloc1 from
being installed at the same time.  See [1] for more on this.

No problem.  Thanks for packaging failmalloc --- it looks like a lot
of fun (and useful, of course) so I look forward to being able to
install it from the Debian archive.
