  Module "xrandr_rotate" makes i3 unusable
  We have seen a case (see #217) when i3 becomes unusable after rotating screen using `xrandr_rotate` module. The symptoms are: `xrandr` process is stalled and only sending SIGCONT to it makes i3 usable again.
  
  This issue is not reproducible for everyone. If you experience a similar behavior, please post here as many details as you can to help us investigate and fix this issue.

  4 Switch between horizontal and vertical screen rotation on a single click.
  5 
  6 Configuration parameters:
  7     cache_timeout: how often to refresh this module.
  8         (default is 10)
  9     format: a string that formats the output, can include placeholders.
  10         (default is '{icon}')
  11     hide_if_disconnected: a boolean flag to hide icon when `screen` is disconnected.
  12         it has no effect unless `screen` option is also configured.
  13         (default: None)
  14     horizontal_icon: a character to represent horizontal rotation.
  15         (default is 'H')
  16     horizontal_rotation: a horizontal rotation for xrandr to use.
  17         available options: 'normal' or 'inverted'.
  18         (default is 'normal')
  19     screen: display output name to rotate, as detected by xrandr.
  20         if not provided, all enabled screens will be rotated.
  21         (default: None)
  22     vertical_icon: a character to represent vertical rotation.
  23         (default is 'V')
  24     vertical_rotation: a vertical rotation for xrandr to use.
  25         available options: 'left' or 'right'.
  26         (default is 'left')
  27 
  28 Available placeholders for formatting the output:
  29     {icon} a rotation icon, specified by `horizontal_icon` or `vertical_icon`.
  30     {screen} a screen name, specified by `screen` option or detected automatically
  31         if only one screen is connected, otherwise 'ALL'.
  32 
  33 
  34 Remarks:
  35     There have been cases when rotating a screen using this module made i3 unusabe.
  36     If you experience a similar behavior, please report as many details as you can:
