- Remove the e2e that did concurrent mgp_* calls on the same transaction
(ATM this is unsupported)
- Fix up the concurrent mgp_global_alloc test to be testing it more precisely
- Reduce the memory limit on detach delete test due to recent memory
optimizations around deltas.
- No longer throw from hook, through jemalloc C, to our C++ on other
side. This cause mutex unlocks to not happen.
- No longer allocate error messages while inside the hook. This caused
recursive entry back inside jamalloc which would try to relock a
non-recursive mutex.
