So I have despaired of getting mutexes, threads and forks to coexist
peacably in Ruby. (As soon as the child process touches a mutex that
existed in the parent… Bad Things can happen.)
So Plan B is to
- spin a thread
- to mind a fork
- that just execs
a new instance of Ruby.
Now I tend to have several versions of Ruby lying around on my Box.
What is the One True Way of finding the path to the instance of ruby
that is currently executing this script?
GNU “Make” is pretty good about this, it has a $(MAKE) variable that
gives the exact path of make that is running.
