Reverted "Leak TypeDescriptor_Init_Impl to avoid problems at exit."

(This reverts commit 0ba6bd3ddc025666a6d4bb0640bf443728b23bd3.)

The problems worked-around there are no longer observed by me, so they
were hopefully only a temporal problem (the real root cause had never
been found back then).  If problems start to pop up again, we'll need
to have another look at this.
