putting my money where my mouth is (re: the novel idea)

[sean finney]

so, in light of last night's discussion, i decided to throw together
a small proof of concept to illustrate my point.  attached are three
files:

	- check_hello.c, a simple "plugin" that prints hello world.
	- a Makefile that illustrates just how easy it is to build a
	  shared object in the way i suggested
	- dltest.c, a program that benchmarks one vs. the other by
	  executing the system/function calls 1000 times and recording
	  elapsed time in microseconds (i'd recommend piping stdout
	  to /dev/null)

this is what i get:

copelandia[~/nagiosplug/plugtest]09:41:03$ ./dltest >/dev/null
dlopen: 131
system: 3698327
