This is the first step in addressing #113 and the initial support of #130. Basically this allows (sub)processes to engage the `pdbpp` debug machinery which read/writes the root actor's tty but only in a FIFO semaphored way such that no two processes are using it simultaneously. That means you can have multiple actors enter a trace or crash and run the debugger in a sensible way without clobbering each other's access to stdio. It required adding some "tear down hooks" to a custom `pdbpp.Pdb` type such that we release a child's lock on the parent on debugger exit (in this case when either of the "continue" or "quit" commands are issued to the debugger console). There's some code left commented in anticipation of full support for issue #130 where we're need to actually capture and feed stdin to the target (remote) actor which won't necessarily being running on the same host. |

tractor
A structured concurrent, async-native "actor model" built on trio and multiprocessing.
tractor is an attempt to bring trionic structured concurrency to distributed multi-core Python; it aims to be the Python multi-processing framework you always wanted.
tractor lets you spawn trio "actors": processes which each run a trio scheduled task tree (also known as an async sandwich). Actors communicate by exchanging asynchronous messages and avoid sharing any state. This model allows for highly distributed software architecture which works just as well on multiple cores as it does over many hosts.
The first step to grok tractor is to get the basics of trio down. A great place to start is the trio docs and this blog post.

No PyPi release yet!
pip install git+git://github.com/goodboy/tractor.gitFeel like saying hi?
This project is very much coupled to the ongoing development of trio (i.e. tractor gets all its ideas from that brilliant community). If you want to help, have suggestions or just want to say hi, please feel free to ping me on the trio gitter channel!
