I've got a similar effect with Garamond Premier Pro, Bitstream Charter,
DejaVu Sans, DejaVu Serif, Nimbus Roman No9 L, Kurier, TeX Gyre Heros,
TeX Gyre Bonum, TeX Gyre Pagella, TeX Gyre Termes, TeX Gyre Adventor.

However, no problem with the following fonts:  TeX Gyre Cursor, Georgia,
Verdana, Times New Roman, Trebuchet MS.

So no, it's not specific to Heros, but it depends on the font used
somehow.

What do you mean by that?  \emergencystretch-30pt seems to behave the
same way as 0pt, that is XeTeX doesn't attempt an emergency pass (tested
on a constructed paragraph that needs the third pass to avoid an
overfull).
