Method of cleanup after termination of a process under a simulated operating system

A method of cleanup after a termination of a client process running in a multi-process environment in which a simulated operating system runs as a process under a native operating system, the method including the steps of:

• upon detecting the termination of the client process, creating a subsystem cleanup process to call a subsystem cleanup procedure of the simulated operating system in a manner that impersonates the client process;
• and
• upon detecting termination of the subsystem cleanup process;
• performing a cleanup of resources of the simulated operating system employed by the client process;
• and
• performing a cleanup of resources employed by the subsystem cleanup process.

A method for cleaning up system resources upon termination of a client process running in conjunction with a simulated operating system as a process under a native operating system, the client process having a cleanup process adapted for the simulated operating system and the simulated operating system having a subsystem cleanup procedure adapted for the native operating system, the method comprising:

• performing a process service which includes the steps of
• detecting termination of the client process;
• and
• upon detecting the termination, creating a subsystem cleanup process which impersonates the cleanup process of the client process and calls the subsystem cleanup procedure of the simulated operating system.
