With a very nice hack, a new hidden configuration option that delays dropped files removal at exit. This still leaks while the project manager is running, but will clear memory as soon as it exits or load something. (reminder, dropped files are reguarly removed after the signal is emitted specifically to avoid leaks, but I prefer hacking the HTML5 config then the project manager).
