- 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.

Creates a new SV. A non-zero C<len> parameter indicates the number of
bytes of preallocated string space the SV should have. An extra byte for a

C<id> is an integer id between 0 and 1299 (used to identify leaks).
