Crash in SDL port on exit

[hboetes]

Upon exiting angband I sometimes get this hang if I press esc right after c-x

Possible dupe #1730

[takkaria]

Assigning open bugs to 3.5 for fixing.

Can't reproduce this and it's after the game has already finished so not a high priority. No longer a blocker.
