      Define a new function process-wait-until-fd-usable; similar to · 9e78a0f2
      dtc authored
      sys:wait-until-fd-usable but uses process-wait so avoids blocking if
      there are other runnable processes.
      
      Redefine the sleep function to use process-wait-with-timeout to avoid
      blocking if there are other runnable processes.

      Merge in changes to the x86 backend from the gencgc branch, allowing · 725ab9ee

      common binaries to be run on both:
      
      * The immediate-stack storage class has been removed, this is
      unnecessary as the descriptor-stack SC can be used. It may have once
      been part of some GC stragety to reduce the number of stack slots that
      needed to be noted for a GC.
      
      * The object allocation has been abstracted and cleaned up. This
      should produce slightly faster smaller code with CGC, and can be
      compiled to support inline allocation with GENCGC.  CGC compiled code
      will run under GENCGC, and GENCGC binaries that don't use inline
      allocation will run under CGC.
      
      * A random hash is now placed in the unused symbol object slot (the
      symbol-hash slot). This saves flushing the info cache at each GC, and
      may have other uses for symbol based hash tables. Should help MP
      safety.
      
      * Common set of static symbols used by both CGC and GENCGC.
      
      * Corrections to the stack-ref VOP; now returns lisp objects not
      unsigned numbers. Required some patches to debug-int.
      
      * Inline unsigned/signed byte 32 to bignum allocation enabled.
      
      * Support for the x86 xadd instruction applied to instance slot and
      symbol values - may be handy for some MP code.
      
      * Bump up the FASL file version from 1 to 2.
