#1038: Input framework memory usage issue with huge files

I am seeing some significant issues with this run (2.1-814). When I
start with a new install (no session state) with an empty but existing
data file the exec size rapidly goes to 9-16G, the CPU runs at 100%
and any additional data added to the data file after start is ignored.

The test is being done on OSX 10.8.4 .

Sorry for the bad news,
