Re: Exec() hangs if 4k written to StdErr, even with StdErr.ReadAll()

The best way I found to avoid blocking is to redirect StdOut or StdErr
to a file, or if you don't need them separate then you can redirect
StdErr to StdOut using the POSIX standard 2>&1 (redirect handle 2,
stderr, to the address of handle 1, stdout), e.g.
dir /b 2>&1
