+linux-user: substantial memory leak when threads are created and destroyed
+Description of problem:
+Substantial memory leak when the following simple program is executed on `qemu-arm`,
+```c
+// compile with `arm-none-linux-gnueabihf-gcc test_qemu.c -o test_qemu.out -pthread`
+
+#include <assert.h>
+#include <pthread.h>
+
+#define MAGIC_RETURN ((void *)42)
+
+void *thread_main(void *arg)
+{
+    return MAGIC_RETURN;
+}
+
+int main(int argc, char *argv[])
+{
+    size_t i;
+    for (i = 0;; i++)
+    {
+        pthread_t thread;
+        assert(pthread_create(&thread, NULL, thread_main, NULL) == 0);
+        void *ret;
+        assert(pthread_join(thread, &ret) == 0);
+        assert(ret == MAGIC_RETURN);
+    }
+
+    return 0;
+}
+```
+Steps to reproduce:
+1. 
+```
+export TOOLCHAIN_PREFIX=arm-none-linux-gnueabihf
+export ARMSDK=/${TOOLCHAIN_PREFIX}
+export SYSROOT=${ARMSDK}/${TOOLCHAIN_PREFIX}/libc
+export CC=${ARMSDK}/bin/${TOOLCHAIN_PREFIX}-gcc
+```
+2. Download the arm toolchain: `curl --output ${TOOLCHAIN_PREFIX}.tar.xz -L 'https://developer.arm.com/-/media/Files/downloads/gnu-a/10.2-2020.11/binrel/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf.tar.xz?revision=d0b90559-3960-4e4b-9297-7ddbc3e52783&la=en&hash=985078B758BC782BC338DB947347107FBCF8EF6B'`
+3. `mkdir -p ${ARMSDK} && tar xf ${TOOLCHAIN_PREFIX}.tar.xz -C ${ARMSDK} --strip-components=1`
+4. `$CC test_qemu.c -o test_qemu.out -pthread`
+5. `qemu-arm -L $SYSROOT ./test_qemu.out`
+6. Observe memory usage keeps ramping up and crashes the process once out of memory.
