When I'm downloading files the behavior of download manager seem to interfere
with other browser action. For example, starting a download halts all activity
for several seconds on my P4/2.4 GHz while the download manager gets going, even
with other downloads already running. I also notice other halts—when downloads
complete for example. The browser should have sufficient threading that these
simple activities would smoothly block only their background thread, leaving the
user unaware of any resource waits. That's the whole purpose of a download manager!

Reproducible: Always
Steps to Reproduce:
Download a file while attempting to continue browsing.
Actual Results:  
Long, annoying complete browser unresponsiveness. No clicks or state changes are
handled. This includes resizes, window repaints, activity in other browser
windows, etc.

Expected Results:  
Fork, fork, fork!
