What I'd like to do is simulate gprof, i.e., simply record the call
stack at timer interrupts and sort out the mess later.  What I can't
figure out, however, is an easy way to figure out the proper
interleaving of the Lua and C stacks.  If I take an interrupt, which C
functions should be profiled for themselves, and which should be
charged to the account of lua_stackedfunction(0)?
