rem OUR GENERATION ONLY (2026-07-27).  The wait loop below used to hold
rem this window open for ANY btl4.exe on the machine -- a second client,
rem the operator's own pod, or an orphan left by a crash.  The window
rem then never printed the sign-off and looked hung: the reported "it
rem leaves the terminal open".  Snapshot the PIDs alive BEFORE we launch;
rem those belong to somebody else and must not hold us here.

rem HANDOFF WAIT (2026-07-25).  The front end does NOT stay resident: it
rem CreateProcess()es the mission generation and ExitProcess(0)s itself
rem (btl4console.cpp).  So OUR child exiting means "the menu handed off",
rem NOT "the game closed" -- without this wait the window announced "The
rem game has exited" while the game was still loading, which reads as a
rem crash to a playtester.  Wait for the handed-off generation(s) to go.
rem
rem NO EXTERNAL TOOLS: `find`, `findstr` and `timeout` are all shadowed by
rem Git-Bash / MSYS / GnuWin32 builds of the same names when those are on
rem PATH (a dev box, or a player who installed git).  The MSYS `find` is
rem the Unix one and dies with "find: '/I': No such file or directory",
rem and GNU `timeout` takes different arguments.  So: parse tasklist with
rem a pure-cmd for/f, and call both helpers by ABSOLUTE System32 path.
rem A genuinely dead exe leaves no process and falls straight through, so
rem the #41 launch forensics above still work.  If tasklist is missing
rem entirely the loop degrades to reporting immediately -- the old
rem behaviour, never a hang.
