What is the state of the Kernel#spawn support in JRuby?
Currently I am using @headius Spoon https://github.com/headius/spoon
which wraps posix_spawn using FFI. This has proven to work correctly
in JRuby 1.6.4, but I haven’t tested it in any older distributions.
Should Spoon work reliably across older versions of JRuby? Is
Kernel#spawn now implemented with posix_spawn, simaliar to Spoon?
