Thread.ignore_deadlock=

Thread.ignore_deadlock = boolean → true or false

static VALUE
rb_thread_s_ignore_deadlock_set(VALUE self, VALUE val)
{
    GET_THREAD()->vm->thread_ignore_deadlock = RTEST(val);
    return val;
}

Returns the new state. When set to true, the VM will not check for deadlock conditions. It is only useful to set this if your application can break a deadlock condition via some other means, such as a signal.

Example

Thread.ignore_deadlock = true
queue = Thread::Queue.new

trap(:SIGUSR1){queue.push "Received signal"}

# raises fatal error unless ignoring deadlock
puts queue.pop
