My report was wrong. The host suffering 
the loop has neither gdb nor lldb 
installed; I must have been looking
at the wrong terminal window.

That promises to be more work than expected.
Since armv7 is Tier 2, I'll have to compile 
the port and learn to set up a package server.
This particular host hasn't the disk capacity 
to host a ports tree.

Neither one. I'll start with gdb.

Agreed, I'll begin by trying to get gdb working.

Stopping and restarting the buildworld process seems to
have either delayed or avoided the loop; the machine is
now up to the point of:

...
Building /usr/obj/usr/src/arm.armv7/lib/clang/libclang/Sema/SemaExpr.pico
Building /usr/obj/usr/src/arm.armv7/lib/clang/libclang/Sema/SemaExprCXX.pico
Building /usr/obj/usr/src/arm.armv7/lib/clang/libclang/Sema/SemaExprMember.pico

At this point it looks doubtful the loop is repeatable. 

Thanks for your guidance and apologies for the goose chase!
