One approach is add dtrace mode on command line.
If the option is enabled, the process will be *all* dtrace probe ready.
But a bit slow (~10%).
Without this option, the process will be not all dtrace probe ready.
This option can be enabled in running with implementation effort.

I think this approach is against dtrace philosophy.
Is it acceptable?
