I'm told that /proc is uniquely a Linux-ism. I certainly haven't noticed
it on Solaris or any Unix SVR4 system. I think Linux borrowed the
concept from Plan9, which was the first OS I heard of that implemented
it (yes, even before OS-9's 1979 introduction the idea of naming all
memory modules, hanging them off a linked list to act as an index and
providing the mdir utility to show you what's in memory.
