Hi,

I have a problem with the x-gw (TIS fwtk) running on a linux system (1.2.9).
The version of fwtk is 1.3
The problem is, that each process, which is spawn for a X-connection, eats up
all the cpu time it will get, even if there is no action over the connection.
I watched the behaviour with a debugger and saw, that a select() is called
(I believe with filedescriptors of the open connection), which returns
immediately. Then read() is called, which says, that 0 bytes where read.
Then the select() is called again, returning immediately, and so on...
So the performance drops down very heavily... :-(
Does anybody know something about it? Do I need a newer release of Linux or
do i need fwtk2.0alpha?

Thanks in advance,
Eike
