So, on linux, I’m forking a new Ruby process. I redirect stdout and
stderr into a file and then I execute another program via ‘system’.
If I background the main Ruby process, the writing to the log file
seems to get halted as (I think) it’s waiting for terminal input
(which it’s not):
$ ./the_ruby_program.rb &
 + Suspended (tty input) ./the_ruby_program.rb
