also i'm getting a lot (> 300) of time-outs when running the script on a
--enable-dbgutil build; i think there are several benign reasons:

* some of the files are very large and template-heavy C++ code like STL
and MDDS relies a lot on inlining so no wonder a build without
optimization is taking some time

* some of the files have HTTP links to images that cause network timeouts

if we could somehow detect that the soffice.bin is still spinning the
CPU we might avoid the first non-problem but not the second.
