In the presence of OS plugins, StopInfoMachException currently
propagates breakpoint stop reasons even if those breakpoints were not
intended for a specific thread, effectively removing our ability to set
thread-specific breakpoints.
This was originally added in [1], but the motivation provided in the
comment does not seem strong enough to remove the ability to set
thread-specific breakpoints. The only way to break thread specific
breakpoints would be if a user set such a breakpoint and _then_ loaded
an OS plugin, a scenario which we would likely not want to support.
