Description Josh Stone 2012-10-11 19:15:15 UTC 
We need stapdyn to set SDT semaphores for those probes to work correctly.  This is already done as a proof-of-concept in dynsdt with a oneTimeCode to increment the short at that address.  We can do the same in stapdyn, but we do need to change tapsets.cxx to output a *file* offset rather than from the load base.
