I assume that just one parent process would be performing this and
then forking a process to handle the job afterwards, right?
Otherwise, you'd have the chance that two processes would read the
queue at the same time and process the same job -- in that case, a
read lock could work.
I've only done forking in C. I saw this in the php manual: "Process
Control support in PHP is not enabled by default. You have to compile
the CGI or CLI version of PHP with --enable-pcntl configuration
option when compiling PHP to enable Process Control support." The
examples in the manual seem like a good starting point: http://
us2.php.net/manual/en/ref.pcntl.php
