Start on amal program

Fix mutex issue in lhs expr which can cause a deadlock when a file has
an error and throws and doesn't close the mutex and another thread waits
for that mutex. The mutex can instead be removed and ignore race
conditions which are uncommon. This should improve memory usage and
performance.
