 * This tool is part of a test that verifies that Pin's "fast" signal handling
 * works.
 *
 * The test runs this tool on an application that delivers lots of signals.
 * The tool inserts a slow out-of-line analysis routine at every BBL,
 * so we expect a lot of the signals to be delivered while inside the analysis
 * function.  The test looks at internal statistics counters to verify that
 * the majority of these signals are delivered using the "fast" algorithm.
 * This validates that Pin's "current location" markers are set correctly, etc.
