Revert "substituted the fork with a pthread"

Browse Source 
This reverts commit 5afeaac470.

execve()  does  not  return on success, and the text, data, bss, and stack of the calling process are overwritten by
that of the program loaded. means we cannot call exec() from a thread, we must use fork.

next try i'll use environment vars to pass mountpoint to forked exec.
