Is writeln thread safe? I’m getting some strange crashes and I’m curious if they’re related to calling writeln on multiple threads.

Is writeln thread safe?
In console application, IMHO yes.
But If you use writeln in a Windows environnement or with LCL widget, it could not be safe.

Unlikely. The output from different threads can be mixed at weird places since it all goes to the same file handle and buffer flushes can interleave, but every thread gets its own copy of the standard IO buffer structures.
