After upgrading to 8.1.0, I seem to be having performance issues that did not
exist on my machine with pervious versions.  I am unsure if these two issues
are related.

Example is included below with descriptions:

1. A file called junk.txt is moved to a folder. This will typically take
around 100 seconds in 8.1.0. Older versions of Octave would perform this task
nearly instantaneously.

2. Trying to save the plot as a pdf will completely lockup Octave every time.
I have left it running for 15 minutes or so and must kill the process.  It
does open the plot and it does create the folder without issues. It also
creates a blank pdf file with the appropriate name in the directory.  If I run
the script using Octave CLI 8.1.0 a message appears while it is running "GL2PS
warning: Unknown token in buffer".


  clear;
  dateandtime=clock;%Parse Date and Time to Create Folder
  yyyy=dateandtime(1);
  mm=dateandtime(2);
  dd=dateandtime(3);
  hh=dateandtime(4);
  min=dateandtime(5);
  sec=floor(dateandtime(6));
  folder=[num2str(yyyy) '_' num2str(mm) '_' num2str(dd) '-' num2str(hh) 'h'
num2str(min) 'm' num2str(sec) 's'];

  mkdir(folder);
  copyfile('junk.txt',folder);

  h1=figure(1);
  x=1:10;
  y=x.^2;
  plot(x,y);

  saveas(h1,fullfile(folder,"testplot"),"pdf")
