- Architectural changes to match information in Windows Internals 4 and other documented sources of information (Windows Internals II by Probert). Code should match Win2003 layout.
- Handle almost any possible process/thread sub structure and add its cleanup code stubs, so that when we actually implement them, we won't forget to clean them up in the process code.
- Add interlocked usage of process and thread flags in order to make everything more thread-safe.
- Better handle cases where threads die instantly, race conditions, and other weird issues.
- Better handle process termination and thread termination.
- Implement NtCreateProcessEx and update PspCreateProcess/NtCreateProcess.
- Improve cleanup of process object in PspProcessDelete.
- Optimize some things like User Thread startup.
- Add some extra asserts, paged_code checks and also user-mode security check.
- Implement helper API PsGetNextProcessThread
- Optimize thread reaper (thanks Filip)
- Do proper referencing/dereferencing of thread/processes (thanks Thomas)
- Document FIXMEs needed for Ps code to be up to standards and complete.
