I am trying to understand why this program behaves differently depending on Y:
#!/bin/bash
rm -f /tmp/par21d9I.tmx
mkfifo /tmp/par21d9I.tmx;
tmux new-session -d true\

exec perl -e '$/="/";$_=<>;$c=<>;unlink $ARGV; /(\d+)h/ and
exit($1);exit$c' /tmp/par21d9I.tmx
tmux version 1.8:
Y=Y prg
#OK
Y=YY prg
#Blocks
Y=YYYYYYY prg
#Blocks
Y=YYYYYYY prg
#OK
tmux version 1.9a:
Y=Y prg
#OK
Y=YY prg
#Blocks
Y=YYYY prg
#Blocks
Y=YYYYY prg
#OK
Any idea why the program hangs for some values of Y?
