General Unix Linux and other Unix-like operating systems use the term "swap" to describe both the act of moving memory pages between RAM and disk. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?

I don't know about HFS+ for mac, but NTFS on windows actually does its best to keep system files and the page file near the center of the physical disc. I don't know how difficult that would be to implement on Ext (I know there are alot of fundamental differences in the way that the two filesystems work), but IMO for pagefiles at least NTFS has the better solution. It is something that the system should be able to figure out by itself based on usage patterns, not something users should have to worry about.
