The 7-10 days is an estimate. I upgraded world/kernel on
Saturday. The previous world/kernel could have been older
than I'm guessing. It could be upto 4 weeks old because
my laptop tends to lag behind the upgrades to my servers.
I would normally use gprof to measure execution times
for the functions I'm writing, but in some quick
testing last night gprof appears to be broken. I'm
seeing a larger variation that I would expect in
self-seconds for the accumulated time for execution
of expf.
