Comment:

 Hello,

 I think this problem is basically that msgq cannot handle asynchronous
 queuing properly, but I don't know where is wrong exactly. Anyway, the
 changes seem to be only for bob and stats, but these almost look OK. There
 are some minor points.

 - A new command 'getstats' is introduced into bob. Is this for internal
 use only? If no, do we need to define it in bob.spec and to document it in
 the manpage of stats and in !ChangeLog? Anyway, when I added 'sendstats'
 to bob at #521, I documented these.

 - I couldn't see any test for the command in bob. Don't we need?

 - If !SessionTimeout raised in stats when waiting for answer from bob,
 should we just ignore it?

 - If bob returns non-zero to stats, wouldn't any message be needed here?

 - Actually 'sendstats' isn't needed. Should we remove it?

 - Do we need to check that argument which bob returns is dictionary type?

 Best
