+Optionally disable jemalloc
+
+Telegram upstream heavily insists you use the jemalloc allocator. This is due
+to the high memory usage resulting from the glibc allocator. It is unknown why
+this affects telegram the way it does, but upstream solved the issue by using a
+different allocator. Initially they used mallocng, now jemalloc.
+
+However, other libcs don't necessarily need this, and as such this should be
+optional. As mallocng is a fork of musl's allocator, and this was used before
+the switch to jemalloc, the musl allocator should still be OK.
+
+Please warn glibc users about disabling jemalloc, don't report bugs about
+memory usage upstream unless you're using jemalloc.
