Short description of error
Hi.
Thank you for poferful software!
When i do a massive import of movie clips all my memory gone http://i.imgur.com/PSV2OyH.png - blender crash
Please release fix for this issue or create a limit of import,
because it is very bad issue.
And, when i work in vse (about 30 min - 1 h.) memory not cleared and sometimes become a situation when all my memory gone too.
(restart blender fix it but it repeated again)
Please improve memory usage/clearing in vse.
