is "svnadmin dump" a safe/atomic backup mechanism?

Let's say that I want to make a backup of a repository by running
"svnadmin dump", and for whatever reason, I can't prevent client
access to the repository during the process.

What happens if a client commit is in progress when I run the "svadmin
dump" command? Will the "svnadmin dump" command fail? If it doesn't,
will the resulting dump file create a consistent repository if loaded
with "svnadmin load"?

What happens if a client attempts to start a commit while the "svadmin
dump" command is in progress? Will the commit block until the
"svadmin dump" command completes, will the commit abort/fail, or will
the commit abort the "svnadmin dump" command? If the former, will the
resulting dump file create a consistent repository if loaded with
"svnadmin load"?

Thanks,
James
