I originally was going to use noprofiled spl routines for profile.h but
switched to inline blocking of interrupts for reasons I can't remember
anymore. Jeff (well, Geocast) were using noprofiled spl routines and at
the time we didn't see any differences with in-practice use (ie, icache
misses vs. function call overhead) so we switched to better align our
code with Geocast's. If indeed this change has made things worse, then
I don't have any problems with it being backed out. Jeff?
