-   XXX LEAKTEST doesn't really work in perl5.  There are direct calls to
-   safemalloc() in the source, so LEAKTEST won't pick them up.
-   (The main "offenders" are extensions.)
-   Further, if you try LEAKTEST, you'll also end up calling
-   Safefree, which might call safexfree() on some things that weren't
-   malloced with safexmalloc.  The correct "fix" to this, if anyone
-   is interested, is to ensure that all calls go through the New and
-   Renew macros.
