Great! That's really amazing work you're doing there.

Seems reasonable, yes.

I assume you've got the FailSafe sources then, so I don't need to send
them to you.
The sap agent signal_sap(), signal_all_sap(), find_all_children()
functions, I'm still sort of proud of those ;-)
The check_db() function probably can benefit quite nicely from hb2's
ability to order start-up even across node boundaries, that will be
useful.
s2_run_command was also a quite useful tool provided in the FailSafe
shellscript wrappers; timeouts, run as user, etc... Sometimes I miss
that when writing OCF RAs nowadays.
