100% of CPU core is used when torrent with mix of I2P and non-I2P trackers is added

[Vort]

This problem can be reproduced with I2P mode disabled.
Just run client_test with default parameters, like this: client_test --alert_mask=all and add such magnet link:
magnet:?xt=urn:btih:70260ca39b2867a59f46d81db85eecb256b9365c&dn=I2P%20Update%202.1.0&tr=http%3A%2F%2Ftracker2.postman.i2p%2Fannounce.php&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce
Then observe CPU usage.

I suspect hang may be related to function libtorrent::torrent::update_tracker_timer.

libtorrent version (or branch): 5ce4c51

Here is the fix - it solved for me atleast in both "mixed mode" as well as "I2P-only mode"

This is not a fix, it is avoidance of the problem.
