failures with parallel tests

[Patrice Dumas]

Hello,

With info tests, when doing parallel tests, with 
make -j8 check
for example, there may be some failures that do not happen for
sequantial tests.  It is not that much reproducible.  There is something
in the log that could point to the issue though:

FAIL: t/body-start.sh
=====================

t/Init-intera.inc: line 21: /dev/pts/36: No such file or directory

The test that fail is not always the same, bug the error message is the
same.
