[lxml-dev] Memory Leak 2.1.1 -> 2.1.2

Hi all, I'm working on a script to replicate it, but using 2.1.2 or more recent results in not freeing any memory when parsing multiple documents in quick succession. The changelog says there was a memory issue fixed, so perhaps this introduced the bug at the same time? I've seen (but not consistently) the lxml memory allocation failed: growing buffer message. Normally it just runs my machine out of memory. Rob
