+add a configure option to control pch usage
+
+Mostly for testing purposes. This also tweaks the dependency to fix a

+Subject: [PATCH] sandbox: accept SANDBOX_LOG vars whatever their values
+
+Commit 40abb498ca4a24495fe34e133379382ce8c3eaca subtly broke the sandbox
+with portage. It changed how the sandbox log env var was accessed by
+moving from getenv() to get_sandbox_log(). The latter has path checking
+and will kick out values that contain a slash. That means every time a
+new process starts, a new sandbox log path will be generated, and when a
+program triggers a violation, it'll write to the new file. Meanwhile,
+portage itself watches the original one which never gets updated.
+
+This code has been around forever w/out documentation, and I can't think
+of a reason we need it. So punt it.

+Subject: [PATCH] libsandbox: clean up open file handles in parent tracing
+ process
+
+Currently, if a non-static app sets up a pipe (with cloexec enabled) and
+executes a static app, the handle to that pipe is left open in the parent
+process. This causes trouble when the parent is waiting for that to be
+closed immediately.
+
+Since none of the fds in the forked parent process matter to us, we can
+just go ahead and clean up all fds before we start tracing the child.
