    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 +,828 K

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

    C:\test>\perl22\bin\perl.exe \perl22\bin\p1.pl [0]{} Perl> print for keys %INC;; Time/HiRes.pm Exporter/Heavy.pm Benchmark.pm Config_heavy.pl overload.pm vars.pm threads/shared.pm Config.pm List/Util.pm warnings.pm warnings/register.pm XSLoader.pm feature.pm DynaLoader.pm strict.pm Data/Dump.pm ActivePerl/Config.pm Scalar/Util.pm C:/Perl22/site/lib/sitecustomize.pl Carp.pm Config_git.pl subs.pm Exporter.pm threads.pm overloading.pm [0]{} Perl>

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