You can achieve that using the `--tty' option to mdb.
Create a new virtual terminal or xterm window,
use the `tty' command to figure out the name of the device
for that terminal, run e.g. `sleep 99999' in that tty,
and then on another terminal/window run `mdb --tty /dev/whatever ./myprog'.

$ mdb --help
Name:	mdb - Mercury debugger
Usage:	mdb [<options>] <executable> [<args>]...
Description:
	...
	By default, all the output of the debugger and the output of the
	program being debugged will be interleaved on the same terminal
	window.  This can be avoided using the `--tty' or `--window'
	options described below.

Options:
	-t <file-name>, --tty <file-name>
		Redirect all of the I/O for the debugger to the device
		specified by <file-name>.  The I/O for the program
		being debugged will not be redirected.
