The man page says that the signal() behavior is BSD, last sentence.
PORTABILITY
The original Unix signal() would reset the handler to
SIG_DFL, and System V (and the Linux kernel and libc4,5)
does the same. On the other hand, BSD does not reset the
handler, but blocks new instances of this signal from
occurring during a call of the handler. The glibc2
library follows the BSD behaviour.
Use sigaction.

read should return on a signal - do you have a test case that shows
differently?
