Instead of forking, try creating a new thread and launching the child via system... maybe your libc system() call will use a different aproach that doesn't need to lock other threads, for instance, a vfork based one.

    Hmmm… The documentation (perlfunc) says:

    Does exactly the same thing as "exec LIST", except that a fork is done first, and the parent process waits for the child process to complete.
