Subject: Clear all objects from the SQLAlchemy session at the start of each request.
X-Git-Tag: 0.1.7~6
X-Git-Url: http://xvm.mit.edu/gitweb/invirt/packages/invirt-web.git/commitdiff_plain/04fa949d023fdb3e9fc623cf6c5aa3d620ff1ca3?hp=a2945267e85c20e2cec87ca5fb470bf51fecfada

Clear all objects from the SQLAlchemy session at the start of each request.

The SA identity mapper isn't *supposed* to be a cache, but it sure can
act like one sometimes.
