connect to external resources (Exchange, GMail):

This errors starts to happen after some requests, and then, we have to restart
the Trinidad server to get rid of it. Some requests later, we get it again.
I have reduced the error to a test case, that always fails at the 50th
iteration. The test fails with an empty rails application (using only rails
3.1.3 gem in the Gemset).

Without rails, it fails at the first iteration.
