Subject: Added calls to GC.AddMemoryPressure() when unmanaged memory is
 allocated for ODE (helps the GC make better scheduling choices), and a call
 to GC.Collect() right before logins are enabled for a region. Although this
 doesn't change actual memory usage, it improves the reported usage from
 OpenSim and the operating system
