+ Flush register windows on sparc.
+
+ This function is in a separate file to prevent inlining. The "flushw"
+ assembler instruction used on sparcv9 flushes all register windows
+ except the current one, so if it is inlined, the current register
+ window of the process executing the instruction will not be flushed
+ correctly.
+
+ See http://bugs.ruby-lang.org/issues/5244 for discussion.
