Such as "never" working? :-)  On i386's panic() has no function epilogue
or return statement, so you have to do these manually to get it to
return.  Then the caller may be missing stack cleanups...  The easiest
workaround is to declare panic() as returning, but this will cause
lots of compiler warnings.
