OK, I think I've found the problem; I have firejail installed, so when I run 
ssh it actually runs firejail, which in turn runs ssh as a child process, and 
so the pid reported by guile doesn't match the pid of the ssh process.
If I replace "ssh" with "/usr/bin/ssh" they match. 

Thanks for your help.
