Tor (started by Vidalia) ignores StrictEntryNodes + EntryNodes

Tor has 3 default EntryGuards. They are different from EntryNodes which are
defined by users.
Tor picks EntryGuards by itself.
*UseEntryGuards **0*|*1* If this option is set to 1, we pick a few long-term
entry servers, and try to stick with them. This is desirable because
constantly changing servers increases the odds that an adversary who owns
some servers will observe a fraction of your paths. (Defaults to 1.)

*NumEntryGuards **NUM* If UseEntryGuards is set to 1, we will try to pick a
total of NUM routers as long-term entries for our circuits. (Defaults to 3.)
