Same here.  For 3.2a1, I looked at the stable buildbots -- unfortunately, three
out of six were offline.  Of the other three, I fixed a few real bugs, and in
the end two of them were green.  The last one, a Windows 7 machine, had some
obscure failures building OpenSSL, about which I consulted Martin and David,
the owner, and some real issues with the new OpenSSL version were fixed, but
in the end it was still red.

So, I think in the end having the buildbots was a success, even if only 2/6
were green :)

two, excepting that thou then proceed to four. Tabs are right out.
