Hi Lorenzo.

Doesn't seem to be the case, unfortunately. During one run of pw.x:

mverissi at rocknroll:~/pseudo_ape/Carbono/pbe/brute_force/rcs_1.20_rcp_1.20/bmod$
free -m
             total       used       free     shared    buffers     cached
Mem:          7934       2636       5297          0        165       1323
-/+ buffers/cache:       1147       6786
Swap:        11444          0      11444

In the one immediately following it:

mverissi at rocknroll:~/pseudo_ape/Carbono/pbe/brute_force/rcs_1.20_rcp_1.20/bmod$
free -m
             total       used       free     shared    buffers     cached
Mem:          7934       2705       5228          0        165       1387
-/+ buffers/cache:       1151       6782
Swap:        11444          0      11444

Even though the runs eat little RAM at a time, I have a few hundred runs to
perform - I suppose by the end of the runs I'll have my ram all gobbled :(
