Valgrind does not allow attaching to a running process.

With some development effort, it may be possible to add such a feature 
(e.g. Intel Pin, quite similar to Valgrind, but not open-source, allows
for this). However, this only would be useful for profiling tools.
For correctness checkers (memcheck, helgrind, ...), its useless, as
these tools need to observe all actions from program start to work.
Thus, afaik, attaching to running programs is not on the TODO list for
Valgrind.
