+REMARKS:
+Function to open our helper device driver, call it and close the file
+handle. Note that we have to open the device driver for every call because
+of two problems:
+
+ 1. We cannot open a single file handle in a DLL that is shared amongst
+    programs, since every process must have it's own open file handle.
+
+ 2. For some reason there appears to be a limit of about 12 open file
+    handles on a device driver in the system. Hence when we open more
+    than about 12 file handles things start to go very strange.
+
+Hence we simply open the file handle every time that we need to call the
+device driver to work around these problems.
