use sockets for scriptlet/hook communication
If a scriptlet/hook dies at the wrong moment it can trigger SIGPIPE,
terminating the process. For pipes, there is no way to prevent SIGPIPE
other than ignoring it process-wide. This can have unintended
consequences in a multi-threaded process. Using send(2) with sockets,
however, allows ignoring SIGPIPE on a per-call basis, leaving other
threads able to make use of SIGPIPE.
