Yes it is.
Set the processes tab to monitor peak memory, threads and handles. (view...select columns... - CPU Usage, CPU TIme, Memory usage, Peak memory usage, virtual memory size, handle count and thread count.) That will give you a good picture of what is going on.
Handles are an issue under higher loads (can exceed OS limits). I am all too familiar. The threading is stable mostly, there are loose handles though, I'm sure.
edit: also explore the monitoring capabilities of: start...run...perfmon.msc
