Sure - I was just sharing what I did to get things working, as I have seen
reports on this from a number of people.

 I should be able to generalise it fairly easily.

Something like this?

    make MAX_CONNECTIONS=10 check

Maybe in the case of cygwin, where it is almost bound to fail without such
restrictions, we could put out a warning if it isn't used.
