memory issue from flash runtime

[lucozhao]

I use flash runtime to upload a 19.5M file from Mac chrome.
Before the plupload, the Google Chrome Helper memory usage was 130M, but after select the file and upload it, the memory was increased to ~450M. Refresh browser still see ~450M memory usage.
I use v2.1.1 release.
My init settings are
var uploader = new window.plupload.Uploader(_.extend({
runtimes:'flash,html5',
browse_button:'',
container:'mx_swf_container',
multipart: false,
max_file_size:'500mb',
url:'/board/upload',
flash_swf_url:'lib/plupload/js/Moxie.swf'
},opts));

After I switch the runtime to html5, the memory issue is gone. But html5 runtime has no progress update from onUploadProgress(). Then I am in a dilemma to use either flash runtime or html5 runtime.

Help wanted. Thanks!

And what do you have in opts object, is it empty? What you describe is not typical, especially the html5 part having no upload progress. Post the whole chunk of code please.
