[drlvm] potential for race condition in jni.cpp jni_init()

[Geir Magnusson Jr]

Trying to solve some of the compilation warnings, I was going through 
jni.cpp.

Do we care that apr_initialize() isn't really protected from multiple 
invocations by concurrent threads?  My read of apr_initialize() is that 
it's not protected either.  I assume someone throught this through?
