> The reason that it's a problem for `Layer`s but not for `Feature`s turns
out to be something of an OGR wart: `GetLayer` returns a pointer to a
layer object that is owned by the `DataSet`, but functions like
`GetNextFeature` return copies of the individual features, which it's up
to you to destroy. You’re already doing that correctly: that's why
`Feature` needs (and has) a `__del__` method but `Layer` does not.
Thanks for the help looking this up, that explains it and reminds me what
I was doing when I wrote it.
> This patch looks great to me, and fixes my problem.
Great! My apologies for letting a segfault slip through, but thankfully
it was found before 1.0.1 -- which this patch will be included in.
