+gdb is not very useful for me, because it doesn't produce backtraces.
+I decode a couple of stack dumps and one seemd stuck in the
+mono_domain_lock() in object_register_finalizer() (seemigly as the
+result of SuppressFinalizer in the Timer.cs Dispose method).
+Another thread was inside a sigusr1 signal handler and stuck
+in the mono_domain_lock call in mono_jit_info_table_find().
+Using a lock-free mono_jit_info_table_find() allows the program to
+continue for hundreds of thousands of iterations at least
+(I just stopped it after a few minutes).
