Subject: mmap question

Hi all,

Ruby 1.8.1
Solaris 9
mmap 0.2.4

I was just futzing with mmap and I tried this:

require "mmap"

# test.txt contains:
# "The quick brown fox jumped over the lazy dog's back"
# three times, one per line.
file = "test.txt"

m = Mmap.new(file,"rw")

pid = fork

fork{
   m.gsub!(/fox/,"badger")
}

Process.wait
m.gsub!(/badger/,"sloth")
m.unmap

This mostly works as expected, except that the 3rd line of the text
file ends up with the last 7 characters chopped off.  What did I do
wrong?

While I'm at it, does anyone have a "really cool tricks with mmap"
paper laying around somewhere?

Regards,

Dan
