Mike Kelly 2ff134eb63 hurd: Interrupted RPC returning EINTR when server has actually changed state. ...

An interrupted RPC call can return EINTR whilst the RPC is still in
progress on the server. Some RPC calls have permanent consequences
(eg. a write() to append data to a file) but a caller seeing EINTR
should expect that no state has changed. The signal thread now stores
the server's reply (which it already waited for) as the interrupted
thread's reply.
