With zsh 2.6 beta17 I'm getting:

10:41% print =(cat ~/.zshrc) =(cat ~/.zshenv) 
/tmp/zshb007F- /tmp/zshb007F-

which is bad news.  The problem is the use of heaps in
getoutputfile(): the filename returned is on a heap which is popped.
A safe fix is to return the ztrdup'd value which is saved in the
jobtable, since that only gets deleted when the file itself is.
(Alternatively, return a dupstring'd version of the ztrdup'd nam after
the popheap, but I think that's unnecessary.)
