I am not able to do this.  This is not because of my series - I have
verified that the same problem appears without it.  It is because of
acquire_lock() in xl_cmdimpl.c, which is related to memory allocation
races.  This really needs to be sorted out :-/, but at least it isn't
a blocker for my series.
