2008/226: mmapfd(2) - mmap file descriptor

[Darren J Moffat]

I find the function name a bit strange.  So strange in fact it made me 
look at the mmap(2) man page to check that it wasn't taking a char* 
rather than an int for the file since I was sure it took and fd.  Since 
mmap(2) already takes an fd.

The mmap(2) versus mmapfd(2) makes me think of fopen(3C) versus fdopen(3C).

As for a better name it looks to me more like mmapv(2), eg like read(2) 
versus readv(2).
