The reason for the bug above is unclear but - Modify pfs_upgrade so that it's result is easier to analyze in case something fails - Fix several minor weaknesses which could cause that a successing test (either an already existing or a to be developed one) fails because of imperfect cleanup, too slow disconnected sessions etc. should either fix the bug or reduce it's probability or at least make the analysis of failures easier.
