do you mean if the current process received a file handle from another process and wanted to close the handle on the remote end?
Yes, that's why there's a source process parameter.
yeah, my fix doesn't cover receiving a file handle (or sending on behalf of another process). there isn't an existing way (that i see) to tell the other process to remove the cached fd
i was hoping to at least fix the race in this case where the current process is sending
