O.K., this is very simple patch that makes ptyread use select. Sven, could you
look at conditions there? It should be O.K. (blocking select can return either
positive value or -1 if interrupted, in which case we simply exit read loop).

With this patch 'make check' has acceptable CPU load.

Attached due to line length.
