It should probably also be remembered that the "fix" would involve either
polling the status by having select() return more often, or using
sigsetjmp/siglongjmp. The cure is definitly worse than the disease.
In a sense the test for errno == EINTR there is redundant since the
backend has arranged that EINTR can never be returned (signals don't
interrupt system calls) and there's a fair bit of code that relies on
that...
Have a nice day,
