a. twister was running for >4h b. terminate twisterd daemon (from twister-html, network options) c. and got:

Ok, good report. We need to have some mutual exclusion between the libtorrent::session (ses) deletion (twister.cpp:729) and command execution (like twister.cpp:433 from getinfo).

In other words: we tried deleting the libtorrent object while it was still being used by getinfo RPC.

I think the proper fix is not a simple mutex on "ses" usage: we don't want an exclusion preventing simultaneous libtorrent access as it would hurt performance. We need either a sort or read-write locker or a pointer container with usage counter. I'm not sure what good boost templates are provided for us to use in this case.

commited fix. please check!
