As I understand things, open2 forks (duplicating all the threads) and calls _exit if there's an error calling exec (causing threads to be exited prematurely in the child). I think your problem is related to that.

And isn't the work directory a per-process state? If so, there's a race condition in your code. 

thread 1: chdir
thread 2: chdir
thread 2: open
thread 1: open    OOPS, chdir isn't as expected

And another bug: You use open2 without waitpid, or do you set $SIG{PIPE} to handle that elsewhere?
