Is swap on a slow disk? Is this behavior different from previous versions of the kernel? Other notable details? The memory management subsystem or perhaps the I/O scheduler (?) is known to not cope very well with low-memory situations when memory being actively used needs to be reclaimed by swapping things out. In an ideal world, we would want the system to remain responsive enough to kill something, but in practice it is hard to figure out how to do that and figure out what to keep in memory. If some details inspire a method of chiseling away at the problem, I can help direct you to an appropriate person upstream to discuss it and point out patches to test. Otherwise, I will probably close the bug, since it would not be clear how to use this knowledge to improve the kernel. Thanks for reporting.
