I'm not at all surprised to find that it isn't being maintained as well as it should as the kernel developers probably don't even think about it anymore. The correct way to do memory management under *NIX is to use anonymous memory-mapped files.

Dunno what you've been reading. Reading the output of "strace" gives me 
a different impression. For example, "strace hla" reads like so:

execve("/usr/hla/hla", ["hla"], [/* 37 vars */]) = 0
uname({sys="Linux", node="reltok1", ...}) = 0
brk(0)                                  = 0x80ba544
brk(0x80db544)                          = 0x80db544
brk(0x80dc000)                          = 0x80dc000
write(2, "Usage: hla options filename(s)\n\n"..., 199Usage: hla options
