I reproduced the error now. When unzip notices that no free disk space 
is left, it asks the user what to do and that's why it hung. I've fixed 
that in pca now - it will show an error in this situation, fail this 
patch and go on with the next one.

That's even uglier than what I had in mind :)

I think it's really the sub-process' (unzip) job to detect the error 
condition, stop and report it back to the caller (pca) which then should 
report extraction process to be failed. Any attempt to foresee such a 
situation in the caller (pca) will be ugly.
