I talked with Martin and he concurred, so beta10 will default to using 
fork().

Martin also brought this comment to my attention in src/m/intel386.h:

/* XEmacs change: John Hughes <john@AtlanTech.COM> says using vfork
   under i386-unknown-sysv4.2 makes C-g sometimes cause a SIGSEGV
   in TTY mode; the problem goes away if you use fork */
#ifdef USG5_4_2
#define vfork fork
#endif
