Build 3095: run_command starts two processes

#1

OS: windows 7 32bit
plugin runs code

        self.window.run_command("exec", {
            "working_dir": questa_dir,
            "file_regex": self.get_pattern_parse_output(),
            "cmd": 'cmd'], # can be any process
            "shell": True
        })

and it starts two processes cmd.exe. In build 3083 works fine (one process).
Maybe something was changed in build system. Does anyone have the same issue?

shell: True is what causes this.

Tried to comment shell=True and to use shell=False, same result.
In plugin I use other process vsim.exe (can be any).

Problem is trickier than I thought.

Plugin executes command

            self.window.run_command("exec", {
            "working_dir": questa_dir,
            "file_regex": self.get_pattern_parse_output(),
            "cmd": 'vsim', '-c', '-do', self.questa_script_path, '-quiet'],
        })

Actually process vsim executes TCL script smth like that one

# routine to show progress, prints dots
set old_time 0
proc printsimstate {} {
    global Now
    global old_time
    set cur_time $Now
    if { $old_time != $cur_time } {
        puts -nonewline stderr "$cur_time "
        set old_time $cur_time
    } else {
        puts -nonewline stderr "."
    }
    after 1000 printsimstate
}
printsimstate

vsim some arguments
quit -sim
# should exit script and start program in gui mode
exec vsim with arguments &

In build 3083 works as expected, in 3095 it emits two processes, one of them keeps printing dots in console.

Issue solved by adding one more vsim specific command at the end of TCL script

quit -f

Still the same code works differently, something was changed in console handler.
