Sorry to mis-characterize the problem.  It's the 389-ds code with the
concurrency concerns, not freeipa.

The fact that the 389-ds code works on other architectures does not
allow us to draw any conclusions at this point.  It really needs to go
through a root cause analysis to determine exactly why it is not working
correctly.  That will in turn tell us if it's the 389-ds code or
something in the compiler (or elsewhere) that is the problem.
