Description

In #5096 that discussed lchans ending up borken on a busy ericsson bts:

"What would probably make sense is some kind of watchdog that would try to un-BORKE BORKen timeslots after a certain time. This can be done by activating a broken sub-slot and releasing it immediately. If the BTS still refuses to activate it, then it's completely BORKen and the second attempt to un-BORKE can be postponed further."
