Nice, you can plug commands into one-another:
(gdb) p $lx_thread_info($lx_current())
$12 = {task = 0xffffffff81a14440, exec_domain = 0xffffffff81a21e00, flags = 0, status = 0, cpu = 0,
preempt_count = 1, addr_limit = {seg = 18446744073709551615}, restart_block = {
fn = 0xffffffff81054cd0 <do_no_restart_syscall>, {futex = {uaddr = 0x0, val = 0, flags = 0, bitset = 0,
time = 0, uaddr2 = 0x0}, nanosleep = {clockid = 0, rmtp = 0x0, compat_rmtp = 0x0, expires = 0},
poll = {ufds = 0x0, nfds = 0, has_timeout = 0, tv_sec = 0, tv_nsec = 0}}}, sysenter_return = 0x0,
sig_on_uaccess_error = 0, uaccess_err = 0}
