Thank you both for your help. It's quite true that I do want to be
interrupted and SA_RESTART is to prevent it.
However it never occurred to me on linux and cygwin the flag would
be defaulted set. Things started to work much better when I
deliberately unset the flag.
It seems to be working quite nicely on cygwin now but I'm now having
some trouble with the "saved" value of the timer which I haven't
sorted out yet. I don't know that it's not my bug.
Thanks for the prod.
