mysql_real_connect() is a blocking function that issues blocking-but-interruptible connect(), read(), and write() system calls. So we'll allow other threads in the VM to run while calling it since it can block indefinitely. This introduces a rb_thread_blocking_region() wrapper for 1.8 which ensures any received signals can be handled gracefully while inside blocking function calls.
