Could be, but I can't say I have really seen pipes being slow under
Linux either. I have a few applications that use pipes to read data
etc.. They all seem quite speedy.

I attached the full output in a archived text file.

I see the following line appear instantly when I hover the mouse over
Sender in the code... Then the delay, then the lots of text output.

This took almost double as long to output in the Debug Window. I
thought my IDE froze or something, then as soon as I wanted to kill
Lazarus IDE, I saw the text dump in the Debug Output window. I include
that output in the attached archive too.

There seems to be lots of failures. I'll send you the xml and log
files in a private message. It's too big to attach in a mailing list
message.

I'm working on that - though slower than I was hoping. I'm busy
implementing a Object Pascal based debugger for FPC (a fork of duby
with lots of code cleanup). Only reading the DWARF debug information
that FPC outputs (I'm not interested in STABS). I'm a totally newbie
when it comes to debuggers, so I had to do a lot of background reading
before I could start. If I have something worth showing, I'll make the
project public. Hopefully somebody like yourself, with good debugger
experience or DWARF knowledge, will then be able to give me some
pointers.

Just the other day I had to do some maintenance work on a old Delphi 7
project. I forgot how wonderful Delphi's debugging was! I didn't need
to write a single log file or console output. The built-in IDE
debugger just worked perfectly.  It's loooooong over due that FPC has
something similar. One cannot have a compiler without a debugger!
