This is a weird one.

mach/site.py", line 1132, in _ensure_python_exe [ 2785s] 0:34.01 raise Exception( [ 2785s] 0:34.01 Exception: Neither a "python" or "python3" were found. This means something unexpected happened during the virtual environment creation and we cannot proceed.

From what I can tell in the code, it simply calls `python3 -m venv --without-pip /some/tmp/dir` [1], and afterwards checks if a python-binary exists in the newly created venv [2]. There seems to be some race condition, when creating the venv. Maybe in the filesystem or in python? I don't know how python creates these, but maybe the process exits before everything is in place? Matej, could you maybe give some input?
