The usage of |posix_spawn()| has been manually disabled because there seems to be a
race condition which cases sporadic failures like this:

######## Errata #002: ########
A workaround was added for a problem with the "multiline" editor mode which
occurs when the edit line becomes longer than the terminal's width and the
terminal cursor is not at position 0 when PS1 is send to the terminal.
For example: The user executes a $ printf "foo"<enter> # the prompt will start
at position 3 instead of 0. If the user enters a command which is longer than
the terminal width and then removes enougth characters that the edit line fits
again into one line the "foo" at the beginning will be overwritten with the
prompt.
The workaround is to add $(printf "%*s\r%s" COLUMNS "") at the beginning of
PS1 set by /etc/ksh.kshrc, this causes the shell to move to the beginning
of the next line if the terminal cursor is not at position 0.
######## Errata #003: ########
A fix was backported to cure sporadic VSC test suite failures. The failures are
generated when command substitutions+functions are executed in a nested manner
- sometimes the return code is non-zero even if the called function explicitly
contains a "return 0"-statement.
