Steps to reproduce:

    Compile fb97457 with:
       CC=clang CFLAGS=" -O0 -g -DEXITFREE " cmake .. -DMIN_LOG_LEVEL=0 -DCMAKE_BUILD_TYPE=Debug -DBUSTED_OUTPUT_TYPE=utf
       -DCMAKE_INSTALL_PREFIX=$PWD/root -DJEMALLOC_USE_BUNDLED=1 -DCLANG_ASAN_UBSAN=ON -DPREFER_LUAJIT=false

    Directory `crash` contains:
    1. unite directory with Shougo/unite.vim@be09b0e
    2. vimfiler directory with Shougo/vimfiler.vim@72c37e8
    3. `init.vim` with a single line which sets `&rtp` to the above two directories (absolute path).

    bin/nvim -u ../crash/init.vim -i NONE --headless -s <(<<< $':split\n:VimFiler\n\C-ww:call garbagecollect()\n\C-w\C-w\C-w')

Steps to reproduce:

    Compile fb97457 with:
       CC=clang CFLAGS=" -O0 -g -DEXITFREE " cmake .. -DMIN_LOG_LEVEL=0 -DCMAKE_BUILD_TYPE=Debug -DBUSTED_OUTPUT_TYPE=utf
       -DCMAKE_INSTALL_PREFIX=$PWD/root -DJEMALLOC_USE_BUNDLED=1 -DCLANG_ASAN_UBSAN=ON -DPREFER_LUAJIT=false

    Directory `crash` contains:
    1. unite directory with Shougo/unite.vim@be09b0e
    2. vimfiler directory with Shougo/vimfiler.vim@72c37e8
    3. `init.vim` with a single line which sets `&rtp` to the above two directories (absolute path).

    bin/nvim -u ../crash/init.vim -i NONE --headless -s <(<<< $':split\n:VimFiler\n\C-ww:call garbagecollect()\n\C-w\C-w\C-w')

…ovim#3

This was a bit of a refactor and a collection of bugfixes from using
this over the last few days. Also fixes neovim#8 and an unreported bug where
deleting signs out from under gitgutter would cause errors (neomake is
no longer deleting signs it didn't create)

The most recent version of neovim uses and array of output lines for
v:job_data[2] instead of a string as before.

Closes neovim#6203

What's going on here, is that loop_close function forcibly closes uv
handles:

    uv_walk(&loop->uv, loop_walk_cb, NULL);

The problem is that neovim's streams keep track of whether the stream
was closed or not, and by pulling the rug from under their feet like
this, they might try to close the uv handle for the second time inside
their callbacks.
