PrintTicket DllHost.exe Memory Climbs

I'm using PrintTickets to print a large number of WPF objects and things are printing fine. We do have a situation that has been reported where the program is using a ton of the dllhost.exe memory and climbs until the machine eventually crashes. I've narrowed it down to creating a PrintTicket and the printqueue.getprintcapabilitiesasxml(). Each time these are called it jumps the memory usage of the dllhost.exe each time by sometimes 3+ MB. Can anyone tell me either how to avoid this if possible or if there is a way to clear it after i know it is being used?

Update: I've created a project with simple this code.

for (int i = 0; i < 100; i++)
{
using (System.Printing.PrintQueue pQueuePrnt =
new LocalPrintServer().GetPrintQueue('HP LaserJet 9050 PCL 5'))
{
using (MemoryStream printerCapXmlStream = pQueuePrnt.GetPrintCapabilitiesAsXml())
{
Console.WriteLine(printerCapXmlStream.Length);
}
}
}


This will result in almost 60 MB in the dllhost.exe that will never go away.
