Clarification. The updateHit is really called several times, with the same
combination of task and address. This ltrace output snippet exhibits the problem:
[22688] call thr->printf(3215026272, 0, 0, 0)\
[22688] call thr->printf(3215026272, 0, 0, 0)\
[22688] call thr->printf(3215026272, 0, 0, 0)\
[22688] call thr->printf(3215026272, 0, 0, 0)\
[22688] call thr->printf(3215026272, 0, 0, 0)\
[22688] call thr->printf(3215026272, 0, 0, 0)
[22688] syscall write(4, 4
, 3086082048)4
[22688] syscall leave write = 2
[22688] leave printf = 2
[22688] leave printf = 2
[22688] leave printf = 2
[22688] leave printf = 2
[22688] leave printf = 2
