Hi all,
this patch adds a new configure variable: --with-test-jobs. The new
variable configures how many tests jobs we run concurrently (aka the
-concurrency flag to JTReg). Today --with-jobs is passed as the
-concurrency flag to JTReg which most likely is too big for most
systems with many cores.
For hotspot, the only "supported" configuration for running the jtreg
tests is with -concurrency:1. However, most machines will run the tests
successfully with more concurrency, but I used a default of 1. For the JDK
tests I kept --with-jobs as the default concurrency since I want to keep
the old behaviour.

Hi Erik,
Your patch looks basically sound. A few comments:
* It would be good if you could add a comment somewhere, perhaps in the
new function in build-performance.m4, that "0" test jobs means "let the
test system use the default".
* You should add TEST_JOBS to the list of INIT_CONTROL_VARIABLES in
InitSupport.gmk, to stop make from complaining on it.
* Also, it would be great if you updated the help message in Help.gmk to
include TEST_JOBS.
