Comment (by mevenson):

 After further analysis, the new plan of attack:

 1.  Continue to deprecate SYS:RUN-SHELL-COMMAND, as the JVM-[56] actually
 seem to provide all the behavior we need.

 2.  Fully support the current signature of the abcl-1.5.0-dev SYS:RUN-
 PROGRAM as extended by Pipping and Olof.  The environment clearing/setting
 will work without alterations.  "All that is needed" is to create an
 {{{org.abcl.util.AsyncIOManager}}} using the non-blocking file descriptor
 framework in {{{java.jnio}}} (introduced in JVM5) to drain/fill
 input/output {{{org.armedbear.lisp.Stream}}} instances.  Pipping has
 collected a thorough test suite for the SYS:RUN-PROGRAM behavior, which
 will be of great use in implementation.

 The use of {{{SYS:RUN-PROGRAM}}} as invoked by {{{UIOP/RUN-PROGRAM}}} as
 the implementation interface

 TODO: transcribe details of SYS:RUN-PROGAM test suite invocation;
 implement {{{ASyncIOManager}}}.
