So you're saying processes are stuck for minutes on end at trying to get memory from the kernel? I find this implausible because relatively simple processes such as ssh and bash shouldn't be getting memory from the kernel at a continuous basis. Unless they're suddenly processing a lot of new data (like me trying to cat /dev/urandom), they should be spending most of the time working with the memory they already have. Especially when all I'm doing is pressing keystrokes in ssh+bash, not even hitting enter. Note that malloc doesn't ask memory from the kernel at every call. Glibc malloc is (in)famously stubborn with caching memory it has gotten from the kernel, hesitant to release it back to the kernel.
