Fifo was simpler than writing three scripts for tcl, perl and python.
And I wanted a clean comparison with Perl waiting for data from stdin,
a zero test case.

Similar results on my machine:

python   one-lined empty loop  rss: 2148  vsz: 3608
perl     one-lined empty loop  rss: 1112  vsz: 2756
tclsh8.3 one-lined empty loop  rss: 1096  vsz: 2316

Strange that starting an empty loop makes such a difference for python.
Anyway, the numbers are in a reasonable range, unlike the 18 MB than
came up in a discussion. Thanks for comparing.

Mit freundlichen Gruessen,
