- The current thread is suspended from execution for the number of _s_e_c_o_n_d_s
- specified by the argument. The actual suspension time may be less than
- that requested because any caught signal will terminate the _s_l_e_e_p
- following execution of that signal's catching routine. Also, the
- suspension time may be longer than requested by an arbitrary amount due
- to the scheduling of other activity in the system. The value returned by
- _s_l_e_e_p will be the ``unslept'' amount (the requested time minus the time
- actually slept) in case of premature arousal due to a caught signal.

- Unlike previous implementations, _s_l_e_e_p is implemented with the _s_g_i_n_a_p(_2)
- system call rather than with _a_l_a_r_m(_2). Therefore, there are no unusual
- side effects with the SIGALRM signal; its effect is like that of any
- other signal.
