Presumably, yes. I wasn't trying with `LLDB_DISABLE_PYTHON`, but with CMake generated Xcode project on Darwin, and region below failed. I didn't examine all instances of `os.remove`, I guess I should have.

How about:
```
def removeignoreenoent(filename):
  try:
    os.remove(filename)
  except OSError as e:
    import errno
    if e.errno != errno.ENOENT:
      raise
    pass
```
and call this function instead of os.remove. We might use a better/shorter name; any suggestions?
