We've mentioned before the idea of dropping Valgrind's libpthread.so, and just doing some low-level clone() interception... would that get around any/all this NPTL/TLS nastiness? That option does have some other downsides, though, particularly it makes it harder to tell tools when interesting pthread events (eg. mutex_lock) occur. N |
