Package: doxygen
Version: 1.8.1.2-2
Severity: normal
I've just noticed that when DOT_NUM_THREADS = 0 doxygen uses n+1 threads to run
dot, with n = number of CPUs available.
The problem with this approach is that when running on simulated targets
(using qemu-user-static) the final number of threads can be counter-productive.
I've found this while investigating why doxygen will completely hang the cpu on
on a qemu-virtualized-mips chroot.
Kinds regards, Lisandro.

I believe that the relevant documentation was added in the 1.6.3-1
release. The current documentation for DOT_NUM_THREADS can be found at:
http://sources.debian.net/src/doxygen/1.8.8-5/src/config.xml/#L3075
It is incorporated into the doxygen-doc package in file
/usr/share/doc/doxygen/html/config.html.
