We could likely add the first, but I cannot see adding the second. An
ISVNRepositoryLocation should not have any knowledge of your
credentials. Other than ones that were created pre-1.0 release before
we removed them.

We have not explicitly set out to serialize access to the adapter.
Can you pinpoint the specific area where you feel we have done this?
We made this change to potentially boost performance slightly, by not
constantly constructing new adapters, and more importantly because we
were not using the JavaHL API properly in that we were never calling
the dispose() method. Doing so would essentially be impossible to add
and get tight. JavaHL itself is threadsafe and it seemed like a lot
better way to work with it.
