Subject: xrefresh server, rb-inotify and ioselect

Hi,

This is of interest for all Linux devs doing web development.

I patched the  xrefresh server so that it runs on Linux. Not everything
is implemented but it is useable: http://github.com/MarcWeber/xrefresh-server
Changes will be merged upstream soon.

The question I have is about IO.select line 97
http://github.com/MarcWeber/xrefresh-server/blob/linux/lib/xrefresh-server/linux/monitor.rb

I think when running this app a long time I get bad file descriptor.
When using a wait time of 0.01 I get this error message very soon.

Is this a known issue? I contacted the author of rb-inotify. He told me
I should rewrite the io select loop using C and see whether the same
problem occurs. However you may just know about this issue without me
rewriting everything in C.. In fact it doesn't hurt me much. I'm
just curious.

So is there someone who wants to try xrefresh on Linux and can verify
this behaviour?

Note:
You have to list each file you want to watch in the config path section.
