  Don't be so dismissive of sampling profilers.  I can see a scenario where
one Lua function has a low execution count but takes more time than another
Lua function that has a higher execution count [2].

[2]	Lua function 1 calls a C function that sucks up CPU time, for
	example.  Then again, I'm talking about the Lua interpreter, not
	necessarily LuaJIT.
