Which version? If you mean 21.4 (the one that ships with FC5), then all this means is that, for whatever reason, your kernel is aways setting up the temacs process with a contiguous address space. The fact that the Linux kernel could set up a process virtual address space with holes in it has to be dealt with anyway.

Although I must admit, a poll of all the vm-gurus in the building couldn't come up with a good reason *why* you would want a discontiguous process address space.
