Maybe now that DBG is said to be operational again i will encounter less problems.
However i have lost hours(days really) on finding a bug that was just a print statement in
a backfill hook function.
I also had trouble with printstatements (PutStr) in the library and interface closing code.
In code using the pipe functions i learned that PutStr() is safe, and Printf freezes the system. How about the experience of old hands?
