But knowing when this patch is implemented means we can _not_ patch
certain applications.  The best example of this is gstreamer.  Gstreamer
is patched to lower its initial thread stack usage to 1 MB since that
was the previous limit.  This severely limits gstreamer.  With the
larger initial thread stack size (something that is not changeable by
individual applications), we no longer need to cripple gstreamer on
-CURRENT.  Therefore, I ask __FreeBSD_version to be bumped so I know
when it's safe to let gstreamer take a full 2 MB of stack on the initial
thread.
