eventlog to report more information about stopping threads because of FFI calls
Currently eventlog file doesn't contain more information about FFI than:
"stopping thread ### (making a foreign call)"
It would be very-very useful if we know what actual foreign calls are made. For example:
"stopping thread ### (making a foreign call to function YYYY)
So we could see which function and how much time is spent on that call. If creation of threads because of in-bound foreign calls (callbacks) have which callbacks are created for it will be very useful, too.
