there 3 files:
	7.1-100		host connected at 100 running -prerelease
	7.1-1000	same but connected at 1000
	7.0-1000	-stable with your 'patch' 
at 100 my benchmark didn't suffer from the profiling, average was about 9.
at 1000 the benchmark got realy hit, average was around 12 for the patched,
and 4 for the unpatched (less than at 100).
