New Revision: 61961
URL: http://svn.boost.org/trac/boost/changeset/61961

Log:
Remove non-blocking on child's pipe file descriptors.

Dan Gohman asked that we not force child's pipe file
descriptors to non-blocking so this commit removes
those fcntls calls.  I tested this change on Darwin,
Linux and Solaris and saw no adverse impact to nightly
build behavior.
