I should emphasise that this isn't a case of a 32-bit process trying
to create a thread in a 64-bit process, or vice versa. Both processes
are 32-bits, running under WoW64.
Other functions accessing the remote process, such as VirtualAllocEx
and WriteProcessMemory, are apparently working correctly; it's only
CreateRemoteThread that fails. Is there a workaround for this issue?
