Bug fixes are not features. :-)

Bug fixes are accepted very late in the release process.  The only 
reason they might ever be rejected is if we think there may be a risk 
that the fix will break other working functionality -- particularly if 
we think that breakage may not be discovered until after the release.

If the fixes involve generic scheduling code, I imagine they would be 
accepted well into RC3 if they were not terribly complicated; if they 
were limited to the arinc653 scheduler itself, they could probably be 
accepted until just before the release.
