Valgrind is great, but slows things down a LOT. lsan (via clang) isn't
quite as thorough but doesn't slow things down as much.

Do you have the full valgrind report? There IS leaks in QGIS.... but
the known ones are harmless (eg the metadata for QgsVectorFileWriter
is leaked, but it occurs only once per session). I also see a lot of
leaks when I run valgrind under Ubuntu because of Unity's dbus menu
integration.

Keen to hear if you do find any leaks inside QGIS itself though!
