I have now using two approaches: using SA_NODEFER, and
releasing the sigmask explicitely, though I presume the
release in systems that know of SA_NODEFER is unnecessary.
I haven't yet checked on what purpose serves the explicite
definition of _POSIX_SOURCE in Solaris systems. I feel
it should be something that the compiler defines, like:
