#161 Exception Handling in TCPStream problem
exceptions occuring during a read from a TCPStream
object may not be correctly propagated to the calling
functions:
Tested system is current debian testing, tested
commoncpp2-libs were the debian-package (1.0.3) and
1.0.8 compiled from the download tarballs.

in #11/#12 there the c-routine getc is called from the
istream class
exceptions occuring in c++-routines can not be
propagated back to their calling routines if there is a
c-routine on the way (see g++-docs)
unsigned char byte;
try {
myStream >> byte;
} catch(...) {
snarfucate();
}
won't catch the exception then (if, for example the
connection suddenly vanishes).
