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.
