I could do it myself in C++ or perl.  Any idea how to do it in tclsh,
short of writing an installable command in C?  In this environment, that
wouldn't be totally impossible, but certainly not my first choice.  I'm
patching gpg into a running system.  I can't find any way to access fd
numbers in tcl.
