From my reading, SQLite locks the entire database file when it is
writing. So if the large commit is writing a lot of data to the file
it could be that the lock window is high. I imagine it is also
possible for the size of the database in the ASF repository to make it
take even longer?

Are we using these features of SQLite?

It seems like our code needs to wait for the lock to clear, at least
for a little bit of time. Of course we also need to do as much as we
can to have the lock window be as small as possible.

It seems like this will be a potential WC-NG issue as well if you have
multiple processes accessing the same WC.
