(The patch fails to compile on Solaris because of this.) I'm also

macro is undefined.

I think a better way to handle this might be to introduce rw_rlimit
and either make it a typedef for struct rlimit when the latter can
safely be assumed to exist (i.e., when _XOPEN_UNIX is #defined in
<unistd.h>), or define it identically to struct rlimit otherwise.

Also, I'm growing increasingly uneasy about the growing number of
global variables used throughout the program. I realize that some
may be unavoidable but I would welcome a patch to reduce their
number and consolidate the rest according their function (e.g.,
all those used to invoke the child process, including the new
