Prezto does not close, have to manually kill

[codeoutin]

Description

Hi, i'm using Cygwin with prezto, which is - compared to oh-my-zsh - really fast and awesome. But i cant close the consoles anymore since some processes still keep running and prevent the windows to close.

Expected behavior

When i click exit i expect the terminal to close and kill all related tasks (zsh, nano, git, ...)

Actual behavior

When i click exit the terminal i see some kind of goodbye message but i will not close. Inspecting the task manager i see a bunch of zsh.exe and minty.exe and sometimes even git.exe and nano.exe which are not probably closed.

This appears sometimes (nothing happens when you click ok):

Steps to Reproduce

1. Install Cygwin + ZSH
2. Install prezto the official way
3. Try to close Cygwin or Mintty - it will not work

To exit Cygwin i / you need to:
Open Task Manager -> kill all zsh processes

Versions

• Prezto commit: a338cba(??)
• ZSH version: 5.5.1 (x86_64-unknown-cygwin)
• OS information: win10

This is probably a duplicate of #1493, roll back to 9f1a41d to prevent this until zsh on Cygwin gets zpty support.
