If you have a window associated with the thread, then you can use the easier
function GetWindowThreadProcessId. Otherwise you can use
NtQueryInformationThread, although it may be simpler to store the thread ID
on creation.

See http://www.codeguru.com/forum/showthread.php?t=355572 for an example
using NtQueryInformationThread. It's a good guess that GetThreadId is a
wrapper for NtQueryInformationThread.
