Thanks!

I got NetBSD truss to be very reliable with multiple threads, but GDB is
misbehaving.

I've compared src/ GDB 8.3 and upstream GDB 8.3.

There are a lot of differences and it looks like a lot of our changes
predate gpl2->gpl3 switch in GDB. I have an impression that sometimes we
unintentionally revert to an older GDB code.

I will start with upstreaming small code chunks first and getting
upstream GDB to work on NetBSD/amd64 with its regression tests... It
should be better long term action than mutating local in-tree version.
