thanks! I'm giving it a run as we speak.
I don't have much of a good test setup here, but I'll try delay checks 
and other things to see how it works, I appreciate this feature.

for those wanting to take this for a spin, run this before running 
./configure:
export CFLAGS="-DEVENT_PROFILER"

I had to muck around a bit to find out how to pass this flag to all the 
makefiles, the export worked for me, and only then did make complete 
successfully with the patch.
