Comment (by andrea):

 My bug8787 branch now has this for munmap(), lseek() and unlink().  For
 strftime(), the most straightforward way would be to make
 format_rfc1123_time(), format_iso_time() and format_iso_local_time() able
 to pass on an error return, but these are called from 88 distinct sites in
 src/or/*.c.  Are we sure changing all of those is the right approach?
