Comment(by sjamaan):

 I think #877 is due to the same underlying problem.  There seems to be
 something strange going on when handling interrupts. I think the reason
 the bug goes away when messing with the continuation is because we're now
 allowing interrupts to get handled via the "regular" way, through the GC
 rather than explicitly by C_pending_interrupt.

 I still not quite grok it, but this seems to be the case.  A fix is by not
 calling C_pending_interrupt, but this would kill the ability to save a
 backlog of interrupts (effectively undoing
