Quoting the fine manual:

  Note that futures are intended for the evaluation of purely
  functional expressions.  Expressions that have side-effects or rely on
  I/O may require additional care, such as explicit synchronization (*note
  Mutexes and Condition Variables::).

IOW, think twice before you use it for something not purely computational.
