It's actually pretty hard for me to tell. There's quite a few
subprojects, some of which I know nothing about and some external
libraries which aren't built by scons.
But I'd guess at least a few thousand.

I believe no more than a handful.

ls -sh .sconsign.dblite
19M .sconsign.dblite

Is there an easy way that I can tell how long each Sconscript file
takes to process.
I have my suspicion that  one particular SConscript file is taking very long.
