;; Known limitations:
;; - If another thread is logging while t is running, these messages will be
;; sent to the port as well, even if they don't come from proc.
;; - In the following example:
;; (with-logging-to-port port level
;; (lambda () (log-warning "ok") 3))
;; (log-warning "not ok")
;; If the logging on the last line is executed before the thread listening
;; to the logs sees the stop message, "not ok" will also be sent to port.
