them so long as there are no finalizers implemented in Python
(\method{__del__()} methods). When there are such finalizers, the
detector exposes the cycles through the \ulink{\module{gc}
module}{../lib/module-gc.html}. The \module{gc} module also exposes
module}{../lib/module-gc.html} (specifically, the \code{garbage}
variable in that module). The \module{gc} module also exposes a way
to run the detector (the \function{collect()} function), as well as
configuration interfaces and the ability to disable the detector at
runtime. The cycle detector is considered an optional component;
though it is included by default, it can be disabled at compile time
though it is included by default, it can be disabled at build time
using the \longprogramopt{without-cycle-gc} option to the
\program{configure} script on \UNIX{} platforms (including Mac OS X)
or by removing the definition of \code{WITH_CYCLE_GC} in the
