Parsing of $(..) expressions is non-optimal. It is
impossible to have any parentheses inside the expression.
I.e.,
$ ksh -c 'echo $(echo \( )'
no closing quote
$ ksh -c 'echo $(echo "(" )'
no closing quote
$
The solution is to hack the parsing clode in lex.c, the
question is how to hack it: should any parentheses be
escaped by a backslash, or should recursive parsing be done
(so quotes could also be used to hide hem). The former is
easier, the later better...

This is because the shell forks a shell to run the (..) command

still has the pipe open.
NOTE: this test provokes a bizarre bug in ksh93 (shell starts reading
commands from /etc/termcap..)
