See https://test.winehq.org/data/patterns.html#user32:msg

Where:
0x03ff == WM_USER-1
5 == ERROR_ACCESS_DENIED
1460 == ERROR_TIMEOUT

0, ERROR_ACCESS_DENIED and ERROR_TIMEOUT are the only three errors that were
reported in the past 6 months.

See also bug 54032 which deals with test_broadcast() sometimes getting
ERROR_INVALID_PARAMETER.
