Author: bde Date: Thu Apr 25 15:48:23 2019 New Revision: 346678 URL: https://svnweb.freebsd.org/changeset/base/346678 Log: Restore doing nothing for calls to VGLEnd() after the first. I broke this in r346631. VGLEnd() clears some state variables as it restores state, but not all of them, so it still needs to clear a single state variable to indicate that it has completed. Put this clearing back where it was (at the start instead of the end) to avoid moving bugs in the signal handling.
