You have to escape the \ in the string...
 so in normal ruby strings:
      '\' = ?? what are you typing?!
      '\\' = \
      '\\\\' = \\
 in gsub replace (the second param):
      '\\' = \ = \
      '\\\\' = \\ = \
      '\\\\\\' = \\\ = \\
      '\\\\\\\\' = \\\\ = \\
 or if you put them in a block instead, they behave as normal strings.

So what you wanted was:
  gsub('\\', '\\\\\\\\')
or:
  gsub('\\') { '\\\\' }
or:
  gsub(92.chr, 92chr * 4)
or:
  gsub(92.chr) { 92.chr * 2 }

backslashes can be a pain :-(
