OTTOMH, the biggest weakness is the "stuck in exit list" feature. This is
more of a reliability and recoverability issue than a real-time issue, but
it is related. In a real-time system, error recovery time is an important
design issue. You want to minimize the cases were a system restart is the
only recovery option.
There's also absolute response time limits which are, more or less, built
into the kernel architecture. However, this is more the case where no
tool is right for all jobs.

You really should scan:

It's a good read.

Sure.
