Are we really seeing a closed and reopened fd ?
And if that's the case it may even be intentional ;-)

because if we're only seeing a closed python file object, we could go
the simpler way:

-        if not context[0]:
+        if (not context[0] or
+            type(context[0]) == file and context[0].closed):
             context[0] = os.open("/dev/urandom", os.O_RDONLY, 0777)

I'll try to reproduce first then test if this simple fix is enough...

Frohe Weihnachten !
