Things get better, but the problem shifts.

For example, the next Saxon release will automatically do 
multi-threading for xsl:result-document (each output document is 
produced in parallel with the others). But I had a test case the other 
day where doing everything at the same time blew the heap, so I had to 
suppress the multi-threading in order to conserve memory. Automating the 
resource trade-offs is the next level, but with diminishing returns I 
don't know if it will ever happen. So users still need to know what's 
going on and turn the dials occasionally.
