A workaround, for now, is to create bash wrapper for the mailer:

#!/bin/bash

cat - | /usr/bin/mail $1 "$2" $3

exit 0


Remarks:

1)  The second command line argument must be enclosed in quotes, or the subject line get broken up.
2)  It looks like there's an oddball issue with POSIX pipes on OSX.  A Perl wrapper, opening a pipe to /usr/bin/mail similarly hangs.  I'm not sure of the difference between that and what bash is doing.  I stand to be enlightened!

Anyway, I hope that helps somebody.
