Variable Documentation

__thread int isomalloc_thread = 0 [static]

make sure isomalloc is only called in pthreads that is spawned by Charm++.

It is not safe to call isomalloc in system spawned pthreads for example mpich pthreads, or aio pthreads. Use the following TLS variable to distinguish those pthreads. when set to 1, the current pthreads is allowed to call isomalloc.
