Sorting a logfile, how would you write it?
264135 [lolz.llolz@g] I've written a little ruby program which can sort logfiles with the
264149 [w_a_x_man@ya] File.open( ARGV.first, "r+" ){|file|
264172 [ryand-ruby@z] your version takes a lot of memory, is slow, and doesn't properly

| | 264235 [w_a_x_man@ya] Of course.  But I'm willing to take that miniscule chance when
| | 264237 [ajsavige@ya ] That may be an acceptable risk for a program written for private use.

  264216 [drbrain@se m] This method uses at least 2x the file size worth of memory.  That's a
  264224 [gregory.t.br] Me too.  Besides, `sort` is still the right tool :)
