I’m trying to launch a new process and have it run in a new window. The process I’m trying to spawn is a console application, and I want a new console window to open, in which that process runs. Ideally the new process would also be detached from the current process, i.e. should not be killed when I kill the main julia process.

I’m trying  
`spawn(Cmd(`$(joinpath(JULIA_HOME,Base.julia_exename())) -i`, windows_hide=false, detach=true))`  
But that doesn’t open a new window… I’m on Windows for this.

Thanks,  
David

libuv doesn’t appear to have any way to enable the necessary CreateProcess flag for this (`CREATE_NEW_CONSOLE`), and even if it did, that flag is mutually-exclusive [1] with the `DETACH_PROCESS` flag implied by `detach=true`. Calling `AllocConsole` [2] from your code after spawning should give a new cmd window.
