winproc

https://github.com/main-path/winproc

winproc is a native extension for controlling Windows processes the way the OS intends: argv-array spawning with exact quoting and per-handle inheritance (PROC_THREAD_ATTRIBUTE_HANDLE_LIST), job objects with kill-on-close so a spawned tree can never outlive you (even across a crash), atomic job placement at creation, ConPTY pseudoconsoles for real interactive terminal I/O, and elevation helpers (elevated?/admin?, ShellExecuteEx "runas", scoped token privileges). Blocking waits release the GVL and cooperate with a fiber scheduler. Windows MSVC (mswin) Ruby only.
