So I tried to patch the credential store with that timeout function and
it seems to solve it! Thanks.

This is easily reproduced if you do a `fetch --all` in parallel on the
same repository (seen on the attached image):

About the timeout, I put it at infinite retries, but should this be
configurable? Or should it be a different default?

There aren't many timeout configurations. I found
"core.filesRefLockTimeout" and "core.packedRefsTimeout", doesn't sound
like something that should be re-used.
Should it be something like this with a different name?
