The root regions are allocated on stack before ruunning gc. The super-sized mailbox may lead to the stack overflow. Each region is 16bytes. The mailbox may contain a 100,000 messages.

The current workaround is to skip gc if there are more than MAX_ROOT_REGS (65535) regions.

Fast VIF may cause an oversized mailbox. Use mailbox_limit option when opening vif to avoid this.
