It's not clear precisely who or what would benefit from it; however, the decreased maximum of 32 swapfiles on i386 is a regression vs. 2.4.x's limit of 64, in whatever sense something no one cares about is actually a regression (in principle they could have merely not spoken up about it). In other words, if someone feels itchy because the number went down from 2.4.x, here it is. If not, I'm fine with leaving it be. -- wli P.S. If desired, I can also send in the code to utilize the extra bits on PAE, or turn things into a config option, or whatever.
