Due to incompatibility of RTL between FPC and Delphi my capturing

BTW what the real reason to make these files as threadvar?
To prevent multiple threads writing to stdin/stdout/sterr at the same
time from corrupting each other's data (all of these text files use an
internal buffer, even when the output is immediately flushed afterwards).

Is not the better way to use something like this:
lock_output();
try
// do something nasty with the buffer
finally
flush(output);
unlock_output();
end;
There is NO other runtimes on this planet instead FPC RTL which take
care of per-thread buffer of output.
It is programmers duty to lock/flush buffer in multithreaded environments.
If FPC wants to be so nice - let's introduce critical section in output
structure.
Any outputs would be suspended until a thread acquires it by write
operation.

Anton
