Hi,

I've committed this patch which corrects a problem with sid-io-stdio. 
Currently, when there is no data available to be read, the gloss 
component cannot distinguish this from EOF. This causes eof to be 
reported by do_sys_read prematurely in some instances.

I've committed this patch which adds an eof pin to the sid-io-stdio 
compoenent which is now checked by do_sys_read when no data is returned 
to ensure that it really is eof.

Let me know if you find any problems.

Dave
