Dear Developers:

we reproduced the extraction of a lipid out of a bilayer reported two 
weeks ago for a mixed system, now for a pure POPC lipid bilayer, using 
the Berger forcefield (gromacs 3.3.1, x86_64).
A lipid is extracted within 100ps when using 8 procs, the bilayer stays 
intact on 4 procs and also when manually distributing the atoms across 
the nodes with the -load option of grompp. A bugzilla with all necessary 
files is submitted.

Best wishes,
