 Implementation for Windows
-  
+
 On windows, a thread is created to wait for data on each pipe.  The
 threads are synchronized with the main thread to simulate the use of
 a UNIX-style select system call.
-  
+
 On Windows9x platforms, a small WIN32 console application is spawned
 in-between the calling process and the actual child to be executed.
 This is to work-around a problem with connecting pipes from WIN16
 console applications to WIN32 applications.
