Give the memberof plugin time to work when adding/removing reverse

When we add/remove reverse members it looks like we're operating on
group A but we're really operating on group B. This adds/removes the
member attribute on group B and the memberof plugin adds the memberof
attribute into group A.

We need to give the memberof plugin a chance to do its work so loop a
few times, reading the entry to see if the number of memberof is more
or less what we expect. Bail out if it is taking too long.

About that FIXME you got there: I'm not sure if it wouldn't be better
to handle the possible exception right in the wait_for_memberof method
(I guess it depends on what exception are we expecting and what are we
going to do with it?). If you want the exception to reach the calling
function, I'd like to see some kind of exception handling in that
function - either to let the user know that the error occurred during
this waiting or maybe to disregard the exception and continue normal

The types of exceptions could run the gambit but I was wondering what
would happen if we were looping and some other user deleted the role.
The next search for it would fail with NotFound. Granted this isn't a
very friendly message to return to someone after adding a member to the
group but it does sort of make sense (someone deleted it concurrently).
It seemed best to just let this filter up to the caller.

Yes, I understand that. But my point was that it would be more user
friendy to catch this exception in the calling function and adjust the
error message to the situation. Otherwise user can get completely
out-of-context error message, like "user not found" when working with
groups or something like that.

Some nitpicking: I'm confused - in the doc string you state that "this
will loop for 6+ seconds" and a couple lines below, you have a comment
"Don't sleep for more that 6 seconds" - is there a mistake ar are these
two statements unrelated?

Yeah, I was afraid that might be confusing. I'll wait .3 seconds 20
times so 6 seconds. There are a few LDAP calls which take a bit of time
as well, so it will be 6+ seconds if it goes the whole time.

Ok, thanks for explanation


Ok, I added a catch-all in case something goes horribly wrong.
