Garbage Collector Threads

[DarioS]

gridss.sh has the following default

jvm_args="$jvm_args \
	-Dreference_fasta=$reference \
	-Dsamjdk.use_async_io_read_samtools=true \
	-Dsamjdk.use_async_io_write_samtools=true \
	-Dsamjdk.use_async_io_write_tribble=true \
	-Dsamjdk.buffer_size=4194304"

I saw the Sydney core facility is using -XX:ParallelGCThreads=${NCPUS} for GATK commands. It was found that garbage collection would be spawning 70 threads which slowed down processing quite a bit. Would such a limit be useful to GRIDSS, too?
