Occasionally hangs on Cleaning... X files.

[kraftwerk28]

When running meson compile -C <builddir>, it will hang on this line until SIGINT interruption. Happens across multiple meson projects. Here's the example log. Also, after interruption, the <builddir> becomes broken and further meson compile ... commands would output something like:

ninja: Entering directory `/home/kraftwerk28/projects/wayland/foot/build'
ninja: error: loading 'build.ninja': No such file or directory

until meson setup <builddir> --reconfigure is executed.

$ meson --version
0.62.1
$ ninja --version
1.11.0

I don't know why it would hang, but interrupting Meson while it is reconfiguring would definitely be expected to break the builddir, because the entire point of reconfiguring is to delete a stale build system and recreate it.

Does this also happen when you run ninja instead of meson compile?

Hi!, I can confirm it does happen when running ninja.

Edit: to be precise, if I wait for a while (a few minutes) it will eventually continue.

I'm also experiencing this, it seems to have to do with pyenv locking up sometimes (I have ninja installed over a pyenv, but also inside a toolbox container). I have a workaround - starting a new bash shell (and thus invoking pyenv) fixes the hang for some reason.
It's possible then that this might be an issue in pyenv, at least in my case.
