Set GC threshold high at start of initialisation

Browse Source 
I did have this in here before and the code to set it back was still
at the end of the file, so not sure what happened there.  I guess I
accidentally removed it at some point.

Before doing anything else, set a higher [[help:gc-cons-threshold][gc-cons-threshold]] (I'm
using 100 MiB here) so that we're not garbage collecting during
initialisation to make startup a little faster. We'll save the
original value to restore it at the end of initialisation.

Now that start-up is finished, [[help:gc-cons-threshold][gc-cons-threshold]] and Now that initialization is finished, [[help:gc-cons-threshold][gc-cons-threshold]] should be set
[[help:gc-cons-percentage][gc-cons-percentage]] need to be set back to reasonable values to avoid back to its default value:
memory usage getting too high.
