Hello Daniel,

FWIW, I'd also like to see Tcl better support huge numbers of socket 
connections. Not sure if it exactly fits into the scope of your project 
though.

I recently worked on a project where Tcl could not be used for (at 
least) this reason - it needed to support many thousand clients on UNIX 
and Tcl's select() based socket polling wasn't likely to cut it (see 
unix/tclUnixNotify.c). Not sure what the Windows situation is.

The difficulty is that even across Unices, there are a variety of 
select/poll replacements - e.g. epoll, kqueues, /dev/poll each with 
their own quirks and limitations.

The dual BSD/GPL licensed C library libev seems like a promising attempt 
to offer a unified interface across Linux/Solaris/BSD - see 
http://software.schmorp.de/pkg/libev.html.
