Sccache server spawned by one user used by another sccache user

[RuijieYu]

$ sccache --version
sccache 0.3.0
$ rustc --version
rustc 1.65.0 (897e37553 2022-11-02)

I have two users that were trying to compile the same Rust crate simultaneously, where both users have configured sccache as the rustc wrapper. User A calls cargo build first, which spawns a sccache server listening on localhost:4226. User B then calls cargo build, sees the socket 4226, and returns a permission-denied error, probably because it is trying to access the cache in User A's home dir.

Is there something already implemented that helps the situation? Apparently I can just run sccache --stop-server on User B before running cargo build, but is there something else that more elegently handles it?

you can use different ports for each user using SCCACHE_SERVER_PORT
