looking in pthread's source code I can see that as an epilogue both pthread_cond_timedwait and pthread_cond_wait will try to relock the mutex by means of __pthread_mutex_cond_lock.

watch
WATCH(8) BSD System Manager's Manual WATCH(8)
NAME
watch -- snoop on another tty line
SYNOPSIS
watch [-cinotW] [-f snpdev] [tty]
DESCRIPTION
The watch utility allows the user to examine all data coming through a specified tty using the snp(4) device. If the snp(4) device is not
available, watch will attempt to load the module (snp). The watch utility writes to standard output.
The options are as follows:
-c Reconnect on close. If the tty observed by watch is closed, automatically reattach to the same tty. If this option is not speci-
fied, watch will request a new tty if running in interactive mode or exit if running without a controlling tty.
-f snpdev
If this option is specified, watch will use snpdev as the snp(4) device. Without this option, watch will attempt to find the next
available snp(4) device.
-i Force interactive mode. Interactive mode is a default if watch is started from a tty. If output is redirected to a file, interac-
tive mode can still be requested by specifying this option.
-n Disable the ability to switch the watched tty interactively. This disables both change requests made with <control-X> as well as
automatic prompting when the current tty is closed or overflows. In all cases where a prompt would be displayed, watch will exit.
The reconnect flags are unaffected by this option. When this flag is used, <control-X> is passed through to the terminal.
-o Reconnect on overflow. The behavior of watch if the observed tty overflows is similar to the behavior if the observed tty is closed.
For more info see snp(4).
-t Print the date and time when observation of a given tty is started.
-W Allow write access to observed tty.
tty Tty may be specified as a tty-style device, such as a pseudo tty device, a virtual console, or a serial line, etc. Names may be pre-
ceded by /dev/.
OPERATION
While running in interactive mode, all user input is discarded except for:
<control-G>
Exit watch.
<control-W>
Clear screen.
<control-X>
Change attached tty, unless this feature is disabled, in which case control-X is passed to the terminal as with other control charac-
ters.

The watch utility first appeared in FreeBSD 2.1.
