From 6c0f20088f81d9d84124c265d58a2a8e7d47b059 Mon Sep 17 00:00:00 2001
From: Neil Schemenauer <nascheme@enme.ucalgary.ca>

Subject: [PATCH] Move call_trace(..., PyTrace_CALL, ...) call to top of
 eval_frame.  That way it's called each time a generator is resumed.  The
 tracing of normal functions should be unaffected by this change.
