I don't know about the feasibility of making one of those marshall
across a place channel but in the meantime does it make sense for you
to read the request on the main place, send the data to a separate
place to process and the send the result back? Or is most of the work

Is there a way to write a network server using places, where separate
client connections would be handled by separate worker places? Since
neither TCP listeners nor ports can be sent over a place-channel, I

Note that this will essentially do the double FS access -- but it

Dear All,
I have a problem.
I try to execute a command line program from my Scheme program.
The stdout and stderr of the command line program should
be redirected to a text-field%. I have one program which
writes to stdout and stderr quite quickly and I get the
following error:
iproc.scm:79:24:
Someone, I forget who, mentioned that the Check Syntax arrows no longer
appear in 5.1.1 under Linux (at least not for me and the other person).
They *do* still work for me in 5.1, so this seems to be a regression in
5.1.1.
I really like the arrows and miss them. Can we get them back soon?

This will print out all files and directories, starting from the
current directory.

You may also want to check out the directory-exists? and file-exists?

For some functions, it depends on the library and configuration
provided by the OS. My impression is that leap seconds are typically
not tracked.

This is wonderful news, thanks. I don't see anything in the way of in-app
documentation, which means going into it you kind of need to know what you're
doing. You can look things up in Safari or a PDF reader, but on the iPhone
switching apps is a bit cumbersome, especially for me since I have
