We already do that.  I bet the Solaris case is more about the lack
of support to find an executable from its pid (/proc/<pid>/exe
in Linux).
Guess one can easily try it, run
gdb
(without arguments, or those -nx -nw that guality uses) and type
attach 19355 # pick pid of some process you can debug
in Linux gdb will find the binary etc.
