Section 2.9.2 describes "Interaction with signals in POSIX" on p.16
"and implementors should attempt to implement MPI so that
signals are transparent: an MPI call suspended by a signal should
resume and complete after the signal is handled."
7.6.2 subsection "Interaction with signals and cancelations"
on p.152 lines 10-11
"The outcome is undefined ... if a thread catches a signal while
executing an MPI call."
is not consistent with 2.9.2 (that is equivalent to MPI 1.1)
for the case that required=MPI_THREAD_SINGLE!
The necessary changes may be done carefully because
MPI_INIT is equivalent to MPI_THREAD_INIT(MPI_THREAD_SINGLE,...)
independent of the returned "provided".
