Appears to still be a problem with GNU gdb (GDB) 7.2.50.20100825-cvs:
Timings for 1000, 10000 and 100000 iterations:
0.05user 0.00system 0:00.06elapsed 104%CPU (0avgtext+0avgdata 0maxresident)k
0.58user 0.27system 0:00.91elapsed 93%CPU (0avgtext+0avgdata 0maxresident)k
6.38user 3.14system 0:09.69elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k
without "watch *$1", the 100000 iteration times at:
0.05user 0.02system 0:00.07elapsed 101%CPU (0avgtext+0avgdata 0maxresident)k
so it's not the loop iteration itself that is taking the time.
