Trunk is incompatible with Windows 7/XP, COM waiting and the entire THandleObject.WaitForMultiple are broken.

Patch: cowait.patch.

Just apply and don’t read further, seriously. >,,,<

See these complaints. Corresponding commit was broken in numerous ways, even if you don’t use COM waits:

• Don’t know when CoWaitForMultipleObjects was introduced, but definitely later than Windows 7 (and XP), CoWaitForMultipleHandles is an earlier alternative.

• CoWaitForMultipleObjects is imported from ole32.dll, not kernel32.dll.

• CoWaitForMultipleObjects signature is completely wrong (and misses stdcall to boot).

• CoWaitForMultipleObjects return value is incompatible with WaitFor*, it needs its own branch.

• THandleObject.WaitForMultiple passes an array of THandleObject instead of array of Windows.HANDLE directly to WinAPI functions, really? :D I also removed Len parameter and changed HandleObjs to open array and made Len = 0 work as Len = length(HandleObjs). (Default value of Len = 0 has no sense, being invalid.)

Moreover, I ventured to remove everything that pertains to wrAbandoned in intbasiceventWaitFor, as only mutexes can be abandoned. On my computer, CoWaitForMultipleObjects does not even support abandonment: acquiring a mutex whose previous owner crashed returns plain S_OK. In any case, events are not mutexes, have no owners and cannot be abandoned at all.
