[vile] Console hang on exit (Win32)

[Rick Sladkey]

My vile friends,

I just got a new Windows 7 64-bit laptop and I've run into a serious
problem with the console version of vile 9.7.  If I just open a
command prompt window, run "vile.exe @nul" to defeat my vile.rc,
vile opens normally.  However if I exit vile with ":q<RET>" the
console hangs.  The display still shows the vile screen text including
the status line and ": q" on the last line.  Task manager shows that
vile.exe is no longer running.  I then have to terminate the console
window.

I admit I've been experiencing a related bug on Windows XP 32-bit for
quite some time but I could never find the time to investigate it and I
simply avoided the cirumstances that lead to it.  Perhaps it can be
reproduced more easily than my Windows 7 issue:

- open a fresh command prompt
- run "vile.exe @nul"
- Shell out to another prompt with ":sh<RET>"
- run another vile "vile.exe @nul"
- exit the second vile
- exit the second command prompt with "exit<RET>"
- observe that the first vile in wedged

I just tried vile-9.7zb with the same results.  I suspect the two
problems are related.
