Description
When using current osmo-stp master, I quite frequently get it into a state where it consumes 100% CPU and infinite loops in osmo_timer_del()
120 void osmo_timer_del(struct osmo_timer_list *timer) (gdb) bt full #0 osmo_timer_del (timer=0x560cea1e4468) at timer.c:120 No locals. #1 0x00007fdcfc1c2fb5 in osmo_timers_update () at timer.c:253 current_time = {tv_sec = 1511203899, tv_usec = 890291} node = <optimized out> timer_eviction_list = {next = 0x560cea1e4480, prev = 0x560cea1e4480} this = 0x560cea1e4468 work = <optimized out> #2 0x00007fdcfc1c35e5 in osmo_select_main (polling=<optimized out>) at select.c:250 readset = {__fds_bits = {0 <repeats 16 times>}} writeset = {__fds_bits = {0 <repeats 16 times>}} exceptset = {__fds_bits = {0 <repeats 16 times>}} rc = <optimized out> no_time = {tv_sec = 0, tv_usec = 0} #3 0x0000560ce974f2a3 in main (argc=1, argv=0x7ffe918b4768) at stp_main.c:208 rc = <optimized out> (gdb) q
So somehow, we're corrupting the timer list :/

It seems that https://gerrit.osmocom.org/4939 solves the problem. More testing required to be sure.
