o Fix handling of interrupted syscalls.

 o Just count missed heartbeats on Indys but don't print a messages.  This
   was a bug by itself.
 o Fix a crash in exit_mmap().
 o Fix scanmem().
 o Fix clear_active_bh(), a ~ was missing causing weak performance.
 o Remove experimental cache instructions from stackframe.h.  It wasn't
   improving performance as I was hoping.
 o Shrink the size of the exception handler routines in uaccess.h.
 o Cleanup, remove dead code in various files.
