goshs is a SimpleHTTPServer written in Go. Prior to version 2.1.0, reads the share token's under , releases the lock, serves the file, then re-acquires the lock to increment the counter. Concurrent requests all read the same / snapshot, all pass the check, and all are served — exceeding the operator's intended cap. Version 2.1.0 patches the issue.
