Comment:

 The bindings were written. However, I am getting a segmentation fault in
 `trac2853` in the `test_find_mapped` unittest in `clientlist_test.py` that
 I'm not able to find the reason for. From the core dump, the segfault
 happens in `ZoneWriter::install()` when `result[1].install()` is executed.
 See the lines that commit `71de47f8d14d274ae2223e56423d6022a3cf0369`
 touches. The segfault happens in the call to
 `ZoneTableSegment::getHeader()`.

 The `ZoneWriterPtr` that the Python `ZoneWriter` wraps around does not
 seem to be invalid. `load()` has also just run on it. It seems that when
 `ZoneWriter::install()` is run, `ZoneTableSegmentMapped`'s getHeader()`
 method is not called which is weird.

 I'm putting this ticket to review. Will the reviewer please look at it?
