This is a more general issue than with the OGR WFS driver. This is common to all
command line utilities. Perhaps worth a ticket indeed.

You can mitigate that by adding MAXFEATURES=xxx . For example :

ogrinfo -al -so "WFS:http://myserver.com/service/wfs?MAXFEATURES=xxx". The
MAXFEATURES parameter will be passed to GetFeature requests. This is somehow
documented in the "Dataset name syntax" of http://gdal.org/ogr/drv_wfs.html :

The minimal syntax to open a WFS datasource is : WFS:http://path/to/WFS/service
or http://path/to/WFS/service?SERVICE=WFS

Additionnal optional parameters can be specified such as TYPENAME, VERSION,
MAXFEATURES as specified in WFS specification.
