will be returned in this case. If there is a message, it will be returned
in plain text. A non-zero value for block will cause the method to only
return an undefined value when an error occurs, e.g. when the core has
terminated. Otherwise it will wait until a message is available before
returning.

=item isCoreAlive

  print "Core has not terminated" if $amamp->isCoreAlive;

Checks if the AMaMP core is still "alive", e.g. if it has terminated.
If it has terminated, 0 is returned. If it is still alive, a non-zero
value is returned. Note that just because the core is no longer alive
does not mean there are no messages left to read.
