Comment (by RJVB):

 In my Tcl scripts, I know put this before the call to `mportinit`:

 {{{
 set runner [thread::create -preserved [list thread::wait]]
 thread::send $runner [list after 250 {puts stderr "Initialising
 MacPorts..."}] timerID
 }}}

 and a single line after that procedure terminate successfully:

 {{{
 thread::send -async $runner [list after cancel $timerID]
 }}}

 Later on I reuse the same thread to install a "patience timer" for
 `mportshutdown`.

 I haven't looked if Tcl has repeating timers that can be set as easily but
 if so that could be a nice thing to have, making it print out something
 periodically to show that `port` is (presumably) not frozen.
