The assumption that <hostname, pid> pair can be used to identify running process (until the pid wraps around and gets reused) does not sound particularly limited Git. Don't container folks solve it without touching individual applications? For example, is it a viable option to isolate UTS namespaces (CLONE_NEWUTS) in addition to PID namespaces (CLONE_NEWPID)?
