Actually,  this works fine for ordinary loops. The problem I 
am facing is how to stop a thread which may sit in blocking
system calls like reading from a (blocking) socket. Is there
any "standard" way to solve this problem? Now, I am using
nonblocking sockets, implementing "timeouts" myself, but it
just doesn't feel right...
