As part of testing the v2.34.0-rc0 release candidate on Cygwin, I've
found this commit -- 05881a6fc9 (t/helper/simple-ipc: convert
test-simple-ipc to use start_bg_command, 2021-09-20), according to my
bisecting -- is causing t0052.1 to fail on 32-bit Cygwin. Somehow this
is only affecting the 32-bit Cygwin build; the 64-bit build is working
as expected.
Specifically, the failure I'm seeing is as below:
```
$ GIT_TRACE=1 sh t0052-simple-ipc.sh -vix

```
I've had a look at the code changes, and cannot work out what might be
being handled differently in 32-bit and 64-bit Cygwin environments.
Given the Cygwin project is considering dropping support for 32-bit
Cygwin anyway, it might not be worth doing anything about this. But I
thought it worth reporting in case there's something obvious to folk
more familiar with this code.
