Originally created by @richardszalay on GitHub (Aug 5, 2019).

NOTE: This is different from, but may be related to, #2230

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.175]
Windows Terminal version: 0.3.2142.0

Steps to reproduce

  1. Open a new Windows Terminal instance
  2. Open a second tab using either the "+" button
  3. Close the new tab using CTRL+W, middle clicking the tab, or clicking the tab's "x"

Repeat steps 2-3 as fast as possible.

Expected behavior

Tabs continue to open and close.

Actual behavior

PowerShell - Most of the time, WT stops responding and interacting with it shows the "WindowsTerminal.exe is not responding" modal

CMD / WSL - WT stops responding for about 1 second and then exits (also happens for PowerShell sometimes)
