Definitively. Now on enabling threading:
- torcs goes from ~23 to ~28 fps (before was ~20 with or without threading);
- glxgears with or without gdb doesn't slowdown any more, however I also don't
get any speedup, fps are all within 1.5% (interestingly gdb no longer prints
the 'New Thread...', 'Thread ... exited' info, it looks like the same path is
always taken);
- openarena without gdb is still a bit slower (~100 vs ~103 fps);
- openarena under gdb is still a lot slower (~76 vs ~103).

(Note that when running under gdb to get correct numbers I add '2>&1 >
/dev/null' or else the thread info printing on console slowdown apps even
