This is a known issue, I should even have a bug somewhere under my name
for it. The related issue is memory usage, e.g. the guile example
required 8GB+ last time I tried for the main part of the scheme system.
This should really get some attention as it is becoming more and more of
a problem, also affecting other categories of software.
