v0.6.1

Added

• Debian packaging [#60]
  • There is now a .deb produced and uploaded as part of the artifacts for each
    release on GitHub.

Changed

• RTS now uses a minimum of 4 worker threads [#263]
  • The default is to use as many worker threads as there are CPUs and set CPU
    affinity to map worker threads to CPUs in a 1:1 fashion.
  • The first core is used to run the eventloop that processes I/O and the rest
    runs the main loop that executes actors.
  • On machines with a low CPU count this can be catastrophic. The extreme
    example being a single CPU machine, which consequently will have 0 worker
    threads executing actors. It will only run the eventloop that processes I/O
    and thus is unable to actually run an Acton program.
  • Even on a 2 CPU machine, which would lead to a single worker thread
    executing actors, this can be quite bad.
  • We now run a minimum of 4 worker threads, 1 for the I/O eventloop and 3
    actor processing threads, to get around these problems.
