[ZODB-Dev] Try and fail connect strategy for zeo/zrpc

[Sidnei da Silva]

| Does't the *already included* zeoup.py do exactly what you are trying  
| to do? See the bin directory of your zope home.

Unfortunately no. It uses ClientStorage, which goes through the 1000's
of lines of the connection dance using connect threads and large
timeouts. Effectively, ClientStorage will retry a connection
'forever'. I just want to see if the port is listening and it smells
like ZEO with the minimal reasonable timeout.
