Okay. I have now reproduced your results with 5.22:

C:\test>\perl22\bin\perl -e"my$s=do{local(@ARGV,$/)='1gb.db';<>}; prin
+t `tasklist /nh /fi \"PID eq $$\"`;"

perl.exe                      2948 Console                    1  1,218

But not from my repl. It has a variety of things preloaded:

One or more of which appear to interfere with this feature, which doesn't bode well. I'll investigate further sometime.
