Not really.  bash reads the whole script before executing it - or at
least it did in my limited tests.  strace would confirm.

My guess is that your $PATH includes a directory that is on the NFS
mounted volume - so when bash looks for e.g. 'sleep', it looks on the
NFS mounted volume and hangs.
Try running the script with "strace -f".  It might be noisy, but it
will show you what is blocking.
