After some internal discussion, we've got another option for folks to 
look at:

https://github.com/fink/fink/tree/branch__CFPREFERENCES_AVOID_DAEMON

cf. https://trac.macports.org/ticket/34221

This sets __CFPREFERENCES_AVOID_DAEMON=1 when fink drops to a non-root 
user during builds, and that seems to get rid of any stalls from 
Fink-built stuff including that from tar (this branch reverts the prior 
change), the one I saw from Java detection, and the one you saw from grep.

Since this does more than just set a couple of environment variables 
only during unpacking of a source tarball, I won't be proactive and 
release this change based only on testing by me. :-)
