Leaked fd into spawned children

Hi,

Steps to Reproduce:
echo 'remote_exec target "ls -l /proc/self/fd/"' >dejagnuleak.exp
runtest dejagnuleak.exp
cat testrun.log

Actual results:
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 0 -> /dev/pts/5
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 1 -> /dev/pts/5
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 2 -> /dev/pts/5
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 3 -> /dev/pts/2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
lr-x------ 1 jkratoch jkratoch 64 Aug 26 21:15 4 -> /proc/25522/fd

Expected results:
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 0 -> /dev/pts/5
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 1 -> /dev/pts/5
lrwx------ 1 jkratoch jkratoch 64 Aug 26 21:15 2 -> /dev/pts/5
lr-x------ 1 jkratoch jkratoch 64 Aug 26 21:15 3 -> /proc/25522/fd

The fd for /proc/25522/fd is apparently correct - the one of ls argument.
