RFC: Test set for systemtap instrumentation

[Jon VanAlten]

Hi,

Sorry my earlier email didn't make it clear, I was hoping someone could take a look at this and see if it is an appropriate addition to icedtea.  Patch is against icedtea6 (from a week ago or so), presumably would look pretty much the same for 7.

cheers,

jon
