deallocvt - deallocate unused virtual terminals
deallocvt [ N1 N2 ... ]
If given no argument, the program deallocvt deallocates kernel memory
and data structures for all unused virtual terminals. If arguments Ni
are given, only TTY’s /dev/ttyNi are deallocated.
A virtual terminal is unused if it is not the foreground console, and
no process has it open for reading or writing, and no text has been
selected on its screen.
