Christian Prochaska a6acab6d0d Synchronize signal context destruction
With this patch, the 'Signal_receiver::dissolve()' function does not return
as long as the signal context to be dissolved is still referenced by one
or more 'Signal' objects. This is supposed to delay the destruction of the
signal context while it is still in use.

Fixes #594.
