I cannot reproduce this, neither on GNU/Linux nor on MS-Windows.  So I
guess this is NS-specific.

I see that ns_select calls block/unblock_input, which makes it unsafe
when more than one thread is running.  It's quite possible that this
is the reason.

I hope some NS expert could take a look at this and fix this.

Thanks.
