Maybe you shouldn't have cut off the other line from my
2-line mail ;)))
The most probable reason for the stalls is the fact that
page_launder (like shrink_cache) will try to write out
the complete inactive list if it's almost full of dirty
pages, so the system will still be stuck in __get_request_wait
seconds after the first few megabytes of the paged out
inactive pages have been cleaned already.
cheers,
Rik
