i just discovered that the RTT::FileDescriptorActivity::hasError() 
function returns true if a file descriptor read was interrupted by a 
System interrupt.

(errno -4), this is afaik not a error in general, the hasError() 
function should only return critical errors, from my point of view if a 
read is too often interrupted the timeout should catch. I would like 
therefore to modify the function that errnor -4 is ignored.

Thougts?

Best,
Matthias
