Fixed, along with another instance later.

Fixed. I was about to push, then got paranoid, so I wrote a few tests
for 'open-network-stream', which gave me a few suprises. I had to add
the following in network-stream-tests.el:

+(require 'network-stream)
+; The require above is needed for 'open-network-stream', but it pulls
+; in nsm, which then makes the :nowait tests fail unless we disable
+; the nsm.
+(setq network-security-level 'low)

otherwise both the old and my new ':nowait t' tests failed. Is that
expected?

Thanks
