  New Revision: 65033


    mjit_worker.c: suppress child process's output properly
    Prior to this commit, some of parent process's output was unintentionally
    suppressed. We couldn't suppress only child process's output with spawnvp.
    Instead of that, this commit uses CreateProcess directly to redirect stdout
    and stderr only for child process.
    As it's dealing with HANDLE returned from CreateProcess, now waitpid macro
    needs to CloseHandle it.
    win32/win32.c: Introduce rb_w32_start_process which is designed for MJIT
    worker. Other similar functions can't be used since they are using ALLOCV
    that may trigger GC, which should be avoided on MJIT worker.
