+=head1 WARNING
+
+Due to the POSIX signals specification (which I wasn't aware of at the time I wrote this module), this module is by nature completely unreliable and will never work properly.
+It is therefore B<deprecated>.
+Please don't use it (if you were actually crazy enough to use it).

 =head1 DESCRIPTION
 
-This module implements a rare form of IPC by sending Morse-like signals through C<SIGUSR1> and C<SIGUSR2>. Both of those signals are used, so you won't be able to keep them for something else when you use this module.

 But, seriously, use something else for your IPC. :)
 
+=head1 CAVEATS
+
+When the same signal is sent several times in a row to a process, the POSIX standard does not guarantee that the relevant signal handler will be called for each of the notifications.
+This will result in malformed messages if the transfer speed is so high that the operating system does not have the time to call the signal handler for each bit.
