Hello,

Thank you Carl and Thomas for the clear explanation.

Still one issue remains.

This was a bit meager description.  This is the full output on the
terminal:

```

After some time during the compilation process, my system freezes for a
long time (CapsLock doesn't light up, cannot move mouse cursor, cannot
switch to vc...).  After about an hour the system is responsive again.
