[#synchronization]
[section:synchronization Synchronization]

In general, __boost_fiber__ synchronization objects can neither be moved nor
copied. A synchronization object acts as a mutually-agreed rendezvous point
between different fibers. If such an object were copied somewhere else, the
new copy would have no consumers. If such an object were ['moved] somewhere
else, leaving the original instance in an unspecified state, existing
consumers would behave strangely.

The fiber synchronization objects provided by this library will, by default,
safely synchronize fibers running on different threads. However, this level of
synchronization can be removed (for performance) by building the library with
[*`BOOST_FIBERS_NO_ATOMICS`] defined. When the library is built with that macro,
you must ensure that all the fibers referencing a particular synchronization
object are running in the same thread.
