It might delay swapping for too long. It seems like a bug in writeback - cp (or whatever program) should be throttled rather than being able to fill up memory with buffered writes. This was supposed to have been improved around Linux 3.2. This sounds a bit like <http://bugs.debian.org/695182>, though that discussion has mostly turned up bugs specific to i386 or to older kernel versions. Please report the bug to linux-mm@kvack.org, cc'ing this bug address and including the OOM kernel log and any VM sysctls that you have changed.
