Comment(by mpatel):
I inserted diagnostic "cout" statements in
`extra_prime_class::~extra_prime_class` and ran a few tests. It seems the
destructor always gets called, but the timing --- and whether `PRIMES` is
actually written to the file system, it seems --- depends on whether I use
the library or pexpect interface.
The pexpect interface reads `SAGE_ROOT/data/extcode/mwrank/PRIMES`. But
it doesn't update this file when I quit the Sage command line. However,
if I run
{{{
sage -c "EllipticCurve([1,0,0,0,37455]).rank(proof=False)"
}}}
then "hg stat", for example, confirms the file has changed.
Would it help to call a `exitprimes` method explicitly, near the end of
`main`? This ''might'' avoid problems related to when the runtime calls
the destructor.
Disclaimer: I'm not at all familiar with eclib.
