It doesn't look like OpenSSL's PRNG is much faster than /dev/urandom if Python keeps a persistent fd:

$ python3.3 prng.py 
loops: 1000000
bytes: 16
/dev/urandom (fd)        1.2181
os.urandom()             3.2892
RAND_pseudo_bytes        1.2924
RAND_bytes               1.2945

Some crypto experts also say that the PRNG of a stock OpenSSL build is sub par. The algorithm is neither standardized by NIST nor carefully developed by a cryptographer. FIPS builds of OpenSSL have a better PRNG.
