You will have to use boost::bind to bind the instance and additional
arguments to your thread.
See for example http://blog.emptycrate.com/node/277.

Seemingly, what you originally wanted to use was the thread constructor
with arguments
<http://www.boost.org/doc/libs/1_49_0/doc/html/thread/thread_management.html#thread.thread_management.thread.multiple_argument_constructor>.
However, notice that it actually will create a copy of your object,
which is not what you want.
You will want to use bind with pointer to members
<http://www.boost.org/doc/libs/1_49_0/libs/bind/bind.html#with_member_pointers>.
So _this_ will refer to your object inside the newly created thread.
