If a thread different than the main thread gets a signal, the bytecode evaluation loop is no longer interrupted at each bytecode instruction to check for pending signals which cannot be handled. Only the main thread of the main interpreter can handle signals. Previously, the bytecode evaluation loop was interrupted at each instruction until the main thread handles signals. Changes: * COMPUTE_EVAL_BREAKER() and SIGNAL_PENDING_SIGNALS() no longer set eval_breaker to 1 if the current thread cannot handle signals. * take_gil() now always recomputes eval_breaker.
