[ECOS] using asserts enabled with linux synthetic target

["Tracy Jones" <tracy at stratalight dot com>]

Hi - Has anyone successfully run the linux synthetic target with asserts
enabled?  

I am trying to do so, but am running into problems.

When the network alarm thread runs and preempts the idle thread, I an
error saying that the idle thread it trying to sleep.  That seems like
an ok thing in this case.  Here's the stack trace.
