Tests show that there is a ~1.5s timer that checks for the presence of WS_EX_TOPMOST and restore it
if it got removed when the timer times out. Manual tests that skip WM_TIMER handling show there is a
1.5s timer of ID 0x4242 keeps firing. The timer stops when its WM_TIMER message gets handled.

Fix Deus Ex: Game of the Year Edition missing WS_EX_TOPMOST after changing resolutions in fullscreen
mode. The application removes WS_EX_TOPMOST from its game window after entering fullscreen.

Test that there is a ~1.5s timer after entering fullscreen mode and restores WS_EX_TOPMOST if it's
missing when the timer times out.

This was actually leaking even before the Cycle Collection was implemented.

This is a small thunk to rewind that preserves the first argument
passed. This is needed because on some versions of GCC, rewind's call to
_unlock_file is tail-call optimized, which modifies the stack.

It can take a while before a new eventlog file is created on Windows. Rather than
waiting for it I chose to remove this test since it seems doubtful that any application
will need to access the file directly.
