multiple users at the same time on one repo...

I'm trying that in my workplace with 5 developers
using  1 central repository and each using lightweight
checkouts.

Yes, when someone is locking the repositories the
other developers get locaking errors and has to wait
(manually).

This could be done, but require extra effort when
integrating work by different developers. I don't
think this approach solve the problem.

This looks like a nice feature to have. This is what
cvs do right?

Another and more serious problem is when some bzr
operation failed (caused by network disconnection, for
instance). Then the repository is still locked the
that particular user. Then the other users can't use
the repositories, since the lock file is owned by the
first user. bzr clear-lock doesn't work with
permission denied. So they need the first user or root
password to delete the lock file.

Any thoughts on this?
