i think trying to debug a spawned process is futile. instead let winedbg or
x32dbg-in-wine launch the process itself.

Unfortunately vs_installershell.exe kept popping up a win32 dialog box error
and/or argument error. inspecting servicehub.config.json reveals:
..."additionalEnvironmentVariables" : { "ELECTRON_RUN_AS_NODE": "true" }

I have constructed a method of debugging the subprocess directly via winedbg:

cd WINEPREFIX/drive_c/Program Files/Microsoft Visual
Studio/Installer/resources/app
ELECTRON_RUN_AS_NODE=true winedbg "C:\Program Files\Microsoft Visual
Studio\Installer\vs_installershell.exe"
./node_modules/microsoft-servicehub/host/HubController.js
5d74f51d8cc5d690c261c26d3e9e3408e060bd352875558b9320be9c213e0610

Then type:

b uv_pipe_init
b uv_pipe_pending_instances
b uv_pipe_bind
b uv_listen
b uv_pipe_listen
c

Sadly uv_pipe_listen cannot be breakpointed (all others work fine).

--------

uv_pipe_init get called 4 times.
uv_pipe_bind gets called once.
The process terminates and uv_listen is not called.

I am currently debugging uv_pipe_init via winedbg, using
https://github.com/nodejs/node/blob/v8.9.3/deps/uv/src/win/pipe.c as a
reference.
