gprof and multi-threaded programs

gprof does not appear to profile multi-threaded programs under Lubuntu:

• View a gprof results file of a multithreaded application: 0.0% of the total time is spent non-idle. But actually, 0.0% of the total time is spent non-idle in the main thread only! The application profiled was GTST, version 0.50

oprofile is said to profile multi-threaded programs under Lubuntu correctly.
