M2Crypto question

According to  <krjackson at lbl.gov>:

;-)

IIRC, M2Crypto's first release had rsa_genkey(). I took it out
while I was trying to get rid of the global PyObject pointers
used to hold callbacks.

I'll probably put rsa_genkey() back in the next release. For now,
os.system() is it.

Cheers.
