ioprofiler/ioapps aborts with Fd 964 is already present in parent fds array...

failing part of strace 
(/home/keruom/fzu/acat2013/lysak.cache.on.new.files/strace.dcap.server.35.head):

16435 1368689283.931320 read(964, ""..., 4) = 4 <0.000047>
16435 1368689283.931444 write(964, ""..., 16) = 16 <0.000046>
16435 1368689283.931566 dup2(210, 964) = 964 <0.000039>
16435 1368689283.931651 close(964) = 0 <0.000038>

What's interesting is that the fd 964 was already opened. Apparently, this is 
ok behavior (man 2 dup2):

       dup2() makes newfd be the copy of oldfd, closing newfd first if necessary, but note the following:

       *  If oldfd is not a valid file descriptor, then the call fails, and newfd is not closed.
