I don't have an exact solution, but I think I know what the problem is.

Cookies are identified by their name (such as "author") and by the 
server domain (such as "neil.eton.ca"). So if two cookies are set 
with the same name and same server domain, there will be a conflict. 
The cookie ignores any subdirectory so neil.eton.ca/pmwiki/ and 
neil.eton.ca/wordpress/  will happily (??!!) conflict.

One solution is to use different subdomains as in pmwiki.eton.ca  and 

Another solution ( and a far better one) is for the programs setting 
cookies to use a unique prefix, such as "pmw_author" and "wp_author". 
I suspect that the PmWiki cookie name could be controlled by the 
config.php file, but that may introduce problems with scripts that 
access the cookie by name. I would hope that most scripts would just 
user the $Author (?) variable inside PmWiki.
