It is interesting to note that WinCVS can use a Tcl intrepreter to
provide access to a CVS "shell".  This comes in handy when you just
can't convince yourself to trust the GUI to do branches/merges
properly.

AFAICT, a non-interactive shell is one which cannot read/write from/to
a tty (has no controlling terminal?).  A non-interactive shell can
hang waiting for input or writing to a non-existent terminal.

See http://www.linuxdoc.org/LDP/abs/html/intandnonint.html for a few
more details.
