As a trivial postscript: starting xterm from Windows with the single line
above is as frugal a start-up as any I have come across: ps gives
      PID    PPID    PGID     WINPID   TTY         UID    STIME COMMAND
     1122    1121    1122       7232  pty0      197609 13:57:34 /usr/bin/ps
     1120       1    1120      12216  cons0     197609 13:57:32 /usr/bin/xterm
     1115       1    1115      11964  ?         197609 13:57:30 /usr/bin/XWin
     1121    1120    1121       4228  pty0      197609 13:57:32 /usr/bin/bash
i.e. just 1 x bash + 1 x XWin + 1 x xterm.

Even the one-line xterm startup
$ xinit xterm -- -nolock -multiwindow
from a bash shell, recently shared here, gives the somewhat lengthy
      PID    PPID    PGID     WINPID   TTY         UID    STIME COMMAND
     1745    1739    1745       3548  ?         197609 14:01:42 /usr/bin/xterm
     1740    1739    1740       6564  cons0     197609 14:01:41 /usr/bin/XWin
     1737       1    1737      10976  cons0     197609 13:59:39 /usr/bin/bash
     1739    1737    1739      12004  cons0     197609 14:01:41 /usr/bin/xinit
     1748    1747    1748       6800  pty1      197609 14:01:44 /usr/bin/ps
     1746    1745    1746      10316  pty0      197609 14:01:42 /usr/bin/xterm
     1747    1746    1747       8820  pty1      197609 14:01:42 /usr/bin/bash
i.e. 2 x bash + 1 x xinit + 1 x XWin + 2 x xterm.

BTW the switch -clipboard is redundant in the proffered line above, its omission
rendering the sequence shorter still.
