The detach of a `tcp` type virtual terminal or a `tap` type virtual
ethernet device can lead to a SEGFAULT core dump, e.g. after a
`cpu0ttb0 det` command.
This is caused by a race condition between the detach run-down and the
implementation of `ReventLoop::RemovePollHandler()`.

+(in commit [1620ee3](https://github.com/wfjm/w11/commit/1620ee3)) or a

+#### Fix
+The culprit was that automatic return type determination for the getter
+lambdas was used. This fails when the called method returns a reference of
+an object. The deduced lambda return type will the object, not a reference.
+Unfortunately this doesn't lead to a compile time error but to a run time error.

+Bottom lime is
+- automatic return type detection for lambda's can be error prone
+- it is safer and also more compact to use `std:bind` as method forwarder
