Thanks.  To track the messages down a bit, I added a couple trace statements 
to unpack_message, and ran the commands

wineserver -k
$WINE notepad &
sleep 1
WINEDEBUG=+relay,+win,+msg $WINE winemine > winemine.log 2>&1 &
sleep 1
$WINE python.exe swpfail-testcase.py
wineserver -k

At the end of winemine.log, I saw

001d:Call user32.GetMessageA(0032fd7c,00000000,00000000,00000000) ret=7ec0e14b
trace:msg:peek_message got type 5 msg 80000001 (WM_WINE_SETWINDOWPOS) hwnd
0x20028 wp 0 lp 41f864
trace:msg:unpack_message got WM_WINE_SETWINDOWPOS
trace:msg:unpack_message line 1209: size 28, sizeof(ps->wp) 40, returning FALSE

It looks like unpack_message is returning false, and the message is
being ignored by winemine, because the size being passed to unpack_message
is wrong?

Looks like this might be a regression caused by

commit 5c652698970c6b8cf14a4515e4ebc6251640e5c2

    user32: Pack the WINDOWPOS structure in messages to allow crossing 32/64
boundaries.

This change was introduced after wine-1.1.41.  Does your test work
with wine-1.1.41?

(Also, what app is this affecting?)
