Comment:

 One thought I had about that last profile, though: SHA1 was at the top of
 the list. OpenSSL's PRNG uses a bunch of SHA1, and is ridiculously slow
 for a userspace PRNG.  If SHA1 turns up at the top of the list again, we
 should investigate whether it's our protocols' uses of SHA1, TLS's uses of
 SHA1, or OpenSSL's PRNG's uses of SHA1 that are most to blame.
