1. setenv/getenv read users data (for that purpose msan already intercepts
getenv)
2. a race between setenv and getenv is a rather frequent bug which we do not
detect in tsan

Some context:
Glibc says:
"Modifications of environment variables are not allowed in multi-threaded
programs"
http://www.gnu.org/software/libc/manual/html_node/Environment-Access.html
POSIX says:
"Since multi-threaded applications are not allowed to use the
environ variable to access or modify any environment variable
while any other thread is concurrently modifying any environment
variable, any function dependent on any environment variable is
not thread-safe if another thread is modifying the environment"
