+@subsection Posix signals
+
+On Posix based systems the @code{libgcj} library uses several signals
+internally. @acronym{CNI} code should not attempt to use the same
+signals as doing so may cause @code{libgcj} and/or the @acronym{CNI}
+code to fail.
+
+SIGSEGV is used on many systems to generate
+@code{NullPointerExceptions}. SIGCHLD is used internally by
+@code{Runtime.exec()}. Several other signals (that vary from platform to
+platform) can be used by the memory manager and by
+@code{Thread.interrupt()}.
