[NTG-context] luaotfload

Hello all,

If I run the following document on a 8 GByte RAM Linux machine.
It takes more than 30 minutes until luaotfload has build
the cache for Sparks-Dotline-Medium.otf. If I run another
Program in the background that it never ends (too less memory).
On my Mac the first run with context (upcoming TL2019) needs 9.5 Gbyte
memory and nearly 100% CPU load to scan the Sparks-Dotline font.
This one is, of course, 400 kB big, but why do we need
more than 8 GByte Ram??

The font files are here:
