/bin/sleep (or /usr/bin/sleep) is a program that basically does
The sleep() function puts the current execution context to sleep, it does this by calling a syscall to invoke the kernel sleep function which atomically
(a) sets a wake-up timer
(b) marks the current process as sleeping
(c) waits until the wakeup-timer fires or an interrupt occurs

sleep(3UCB) SunOS/BSD Compatibility Library Functions sleep(3UCB)NAME
sleep - suspend execution for interval
SYNOPSIS
/usr/ucb/cc [ flag ... ] file ...
int sleep(seconds)
unsigned seconds;
DESCRIPTION
sleep() suspends the current process from execution for the number of seconds specified by the argument. The actual suspension time may be
up to 1 second less than that requested, because scheduled wakeups occur at fixed 1-second intervals, and may be an arbitrary amount longer
because of other activity in the system.
sleep() is implemented by setting an interval timer and pausing until it expires. The previous state of this timer is saved and restored.
If the sleep time exceeds the time to the expiration of the previous value of the timer, the process sleeps only until the timer would have
expired, and the signal which occurs with the expiration of the timer is sent one second later.

Use of these interfaces should be restricted to only applications written on BSD platforms. Use of these interfaces with any of the system
libraries or in multi-thread applications is unsupported.
SIGALRM should not be blocked or ignored during a call to sleep(). Only a prior call to alarm(2) should generate SIGALRM for the calling
process during a call to sleep(). A signal-catching function should not interrupt a call to sleep() to call siglongjmp(3C) or longjmp(3C)
to restore an environment saved prior to the sleep() call.
WARNINGS
sleep() is slightly incompatible with alarm(2). Programs that do not execute for at least one second of clock time between successive calls
to sleep() indefinitely delay the alarm signal. Use sleep(3C). Each sleep(3C) call postpones the alarm signal that would have been sent
during the requested sleep period to occur one second later.
