A program of mine using guile-2.0.11 fails whenever a signal occurs
while a call to select is blocking, with this error:

According to the mailing list exchange at
http://lists.gnu.org/archive/html/guile-rpc-bugs/2014-05/msg00001.html ,
this was fixed in guile >= 2.0.10. However it is still present (or back
as a regression) in guile-2.0.11.
The EINTR-safe wrapper mentioned in the mailing list exchange fixes it
for me in user code, but it would be nice if it were not necessary and
guile handled EINTR itself.
