Example: Listing spooled files synchronously

/////////////////////////////////////////////////////////////////////////
//
// Example that shows listing all spooled files on a server synchronously.
// Listing synchronously does not return to the caller until the complete list
// is built. The user perceives a slower response time then listing asynchronously.
//
