 Actually, you don't.  Just have redundant checks.  The outer check (in
 getHeaderDateField) doesn't have to be synchronized, because we do a
 properly synchronized in the init function.
 
 We use this same idiom elsewhere in libgcj.  This gives good
 performance in the common case (no sync needed), but is also
 guaranteed to be correct.
