Project completed, but base.exe still exists, using memory

[Cyrix]

When my project completes, the base.exe is still in the task manager for a while, using memory.
Is there a way to shut down that process as soon as project completes, releasing memory immediately without delay?

Since start of bases is required time and resources. Thats why they continue to work several minutes (5 mins) after last project's execution.
Is this critical for you?
