changes in sbcl-1.0.30 relative to sbcl-1.0.29:
  * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
    SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
    of SB-THREAD:THREAD-ERROR-THREAD.
  * new contrib module: SB-QUEUE provides thread-safe lockless FIFO queues.
  * new feature: docstrings for local and anonymous functions are no longer
    discarded. (thanks to Leslie Polzer)
  * new feature: SB-THREAD:SYMBOL-VALUE-IN-THREAD provides access to symbol
    values in other threads.
  * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
    about object allocation.
  * optimization: division of a real float by a complex float is implemented
    with a specialised code sequence.
  * optimization: MAKE-INSTANCE with non-constant class-argument but constant
    keywords is an order of magnitude faster.
  * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
    in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
    methods, and similarly for non-standard metaclass classes as long as there
    are no methods additional on MAKE-INSTANCE.
  * optimization: more efficient type-checks for FIXNUMs when the value
    is known to be a signed word on x86 and x86-64.
  * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
    and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
    Paul Khuong)
  * optimization: compiler is smarter about delegating argument type checks to
    callees.
