There should be little doubt that cryptographically strong PRNGs exist
which are just as performant as whatever ridiculous MD4 hack is being used
now. Clearly there are cryptographers falling over themselves to try
provide the code to Linus & Co.; he's just not hearing it.
If so, they're not doing it in that thread. Matt presented a PRNG that was
twice as slow
as the existing (crappy but cheap) MD4 one, to be
used in time-critical contexts like process execution. That's not going to
fly, given that that path has attention paid to every last cycle.
