           Version: unspecified
          Hardware: x86-64

ws2_32:sock - test_close_events() sometimes misses the close event on Windows:

sock.c:6845: Test failed: got events 0
sock.c:6858: Test failed: got -1
sock.c:6872: Test failed: got events 0
sock.c:6890: Test failed: expected timeout

See https://test.winehq.org/data/patterns.html#ws2_32:sock

This happened 9 times in the past 8 months, mostly on Windows 7 but it did
happen once on Windows 10:
* 2022-12-14 win7_newtb-w7u-adm
* 2023-02-08 win22H2_fgtb-w10pro64-64
* 2023-02-22 win7_newtb-w7u-de
* 2023-03-17 win7_newtb-w7u-de
* 2023-03-27 win7_newtb-w7u-2qxl
* 2023-03-27 win7_newtb-w7u
* 2023-05-04 win7_newtb-w7u
* 2023-05-10 win7_newtb-w7u-es
* 2023-06-29 win7_newtb-w7u

There are also two cases where the second events check does get an FD_CLOSE
event:

sock.c:6697: Test failed: got events 0
sock.c:6710: Test failed: got -1
sock.c:6712: Test failed: expected timeout
sock.c:6712: Test failed: got events 0x20
