re you running? Perhaps there's something funny about my
build? I don't know anything about distributed/places internals
here, I'm just guessing.
I've tested this on Fedora 17 x64, and on an amazon stock x64 ec2
machine.

The following thunk example works for me.
Uncommenting the message-router line will pump back stdout and stderr
from the remote node so you can see any errors that may be occurring at
the remote-node.
You will have to kill the message router by hitting CTRL-C when you want
to end the program.
Nevermind, my bad, I was using a "uninstalled racket3m" binary.

I'm not sure I understand your question.
But you need to wrap your input events with handle-evt or wrap-evt so
you can close over state that helps you distinguish the events when sync
returns.

Racket threads are green or user threads, they are not scheduled by the
operating system.
Blocking on a socket in XNextEvent blocks the entire Racket VM.
You need to use XConnectionNumber to get the X socket file descriptor

I'm working on distribute places.
The first version should hit git later today as racket/place/distributed.
The abstraction over places is working pretty well.
The abstraction over threads is planned but not started yet.

This is the magic incantation I use to use with valgrind.
valgrind --tool=memcheck --db-attach=yes

the --vex-iropt-precise-memory-exns=yes is important for running racket.

In the Drracket case, I'll detect that that the current-error-port isn't
a file port or racket pipe and set up an IO pump that
pumps a place's standard IO ports into the current Drracket ones.
I think that sh

A deep namespace-copy could be useful in that scenario.
