Wait, that sounds familiar!

My bet is that fc-cache runs in the background to regenerate font
index "every now and then", so that one can use any given font on the
system.

This doesn't happen on Mac on Linux since fontconfig database update
runs independently in the background. But if gnuplot is compiled with
fontconfig under windows it first checks when the database has last
been generated and if enough time elapsed, it regenerates the database
which may take pretty long (depending on the number of fonts available
on the system).
