Details

As Jan noted in bug 805877 comment 12, we can properly handle Baseline->Ion OSR in the presence of background compilation.  When the fallback stub detects a background compilation, it attaches an optimized stub to the chain that checks for this condition.  If the background compilation is still ongoing, then the optimized stub returns, otherwise it yields to the fallback stub which then performs the compilation, if possible.
