Yes, I think it's something along those lines. POSIX doesn't specify how 
signal numbers and exit statuses are shoehorned into the 'int' status 
updated by waitpid; apps are supposed to use WEXITSTATUS etc. to 
retrieve the info from that 'int'. I think that Perl tries to 
standardize this so that Perl apps just one way to shoehorn. One 
possibility is that the version of Perl shipped with Solaris is so old 
that it predates this Perl standardization. It is a bit of a mess.
