[PATCH v6 1/2] win32: close handles of threads that have been joined

["Seija Kijin via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Seija Kijin <doremylover123@xxxxxxxxx>

After joining threads, the handle to the original thread
should be closed as it no longer needs to be open.

This change makes the function POSIX compliant.
