I asked for symbols when I did the opreport, but for libpython, it
didn't produce a by-symbol breakdown, which

Decided this evening to grab some quick profile data for a uhd_fft.py,
running at 50Msps from a USRP2.
The kernel was occupied 41% of the time--no great surprise. Handling

The next largest chunk was libc (memcpy_sse) 12.5%
Then uhd (convert_sc
