Favor IO.select over IO#wait since the latter makes another ioctl syscall (which we'll make anyways for IO#nread). Having BasicSocket#recvmsg and recvmsg_nonblock detect the buffer size requires extra syscalls, so pass explict maxmesglen, flags, and maxcontrollen args to elide auto-detection since we already have the buffered amount from IO#nread. This cuts more syscalls from the "dtas-tl cat" invocation with larger tracklists.
