+Subject: [PATCH] Fix regression wrt Lua reinitialization (RhBug:1958095)
+
+Commit 2579d3e5ad5d713f2c161b9fb4835366ea4ea291 started storing the Lua
+context in the spec, but this leads to problems as what is actually a
+global context is now stored in two places, and can get out of sync.
+So if you parse a spec, and then reset the global context, you get a
+fancy segfault when the freeing the spec because it's pointing to
+la-la-lua land.
+
+Revert back to always using the global Lua handle.
