in thread fork() interferring with backtick

Specifically the backtick command line finds a list of .makelist files in the subdirectories of $dir - hence the array @makelists. What I am finding is the fork call truncates the @makelists in some cases, but repeatably in the same spot for particular directory calls. i know this by adding a print $makelist."\n", just before the ProcessMakeList call. however if i move the fork call before the backtick command the array is preserved.

    If output from external command is truncated, maybe it's this bug (in perl 5.14 ):

    i.e. data received from pipe can be truncated if SIGnal received (and you have signal handler, thus you are affected). I suggest check $! after backtricks call.
