<p>At <code>$work</code>, we have built an API with Dancer that generates PDF documents and XML files. This API is a critical component of an insurance enrollment system: PDFs are generated to deliver to the client in a web browser 
immediately, and the XML is delivered to the carrier as soon as it becomes available. Since the XML often takes a significant amount of time to generate, the job is generated in the background so as not to tie up the 
application server for an extended amount of time. When this was done, a homegrown process management system was developed, and works by <code>fork()</code>ing a process, tracking its pid, and hoping we can later successfully
reap the completed process.</p>
