For the standard function call sequence you'll want to look at
server_initialize_subsystems() in src/server/pvfs2-server.c. This is part of
what occurs during server start. I do see BMI_set_info() is called with the
TCP options called regardless of BMI module type, I'm not sure offhand why
that is.

In addition to the initialization in the above function a server tries to
contact other servers in order to fill their precreate pools (see
precreate_pool_launch_refiller() in the same file). I'm not sure if this is
what's causing the testcontext you're seeing or not. Does that help?
