No, as of today there's a single thread handling dissection. More than
that, today many dissectors use global variables during dissection.
Which is a serious impediment to multithreading.
One day we might want to modify the way dissectors are called passing
to the invoked disssector a data structure in which to contain its
state data, Until that day, and any other days needed to change the
700 or so dissectors in there, I think the only way is a single
thread.
