/* If an event is countable but you've exhausted the counter resources

and you try to add an event, it seems subsequent PAPI_start and/or

PAPI_stop will causes a Seg. Violation.

   I got around this by calling PAPI to get the # of countable events,

then making sure that I didn't try to add more than these number of

events. I still have a problem if someone adds Level 2 cache misses

and then adds FLOPS 'cause I didn't count FLOPS as actually requiring

2 counters. */
