sbcl 1.0.38 released

Hi,

I've just tagged CVS and put sbcl-1.0.38 up for download on Sourceforge.
The freeze was somewhat slushy this time round; I hope there won't need
to be brown paper bags handed around the development team, but please as
ever report any problems encountered with the release.

Best,

Christophe

changes in sbcl-1.0.38 relative to sbcl-1.0.37:
  * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
    like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
  * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
    contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
  * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
    SB-THREAD:GRAB-MUTEX.
  * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
    contain additional data structures and tools for concurrent programming;
    at the moment it contains a lock-free queue, and a lock-free mailbox
    implementation.
  * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
    GET-MUTEX but takes &key rather than &optional parameters.  Also added
    :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
    BSD.
  * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
    SB-THREAD:WAIT-ON-SEMAPHORE.
  * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
    SB-EXT:ATOMIC-INCF.
