Port hanging (unresponsive to Ctrl+C, need SIGKILL)

[Leonardo Brondani Schenkel]

Hello,

I have been working on an update to the Free42 port, which I just opened 
a PR for:
https://github.com/macports/macports-ports/pull/486

However I am experiencing something I never encountered before, which I 
have been unable to troubleshoot on my own: once the `xcodebuild` 
command completes with BUILD SUCCESSFULL, the `port` command simply 
hangs and becomes unresponsive to Ctrl+C. I need to send a SIGKILL from 
a different terminal in order to kill it. I cannot figure out why this 
is happening.

Can a member of the list help me out with the above? First to see if 
this happens to you as well, and then helping me getting to the bottom 
of it?

While you're at it, any other comments you may have about the PR are 
more than welcome.

Thanks,
// Leonardo.
