Ilya, hi.
+1 from me. We should not worry about weird user actions. Direct calling
of GC looks unusual today. Suggestion of forced disabling manual
System.gc() looks useless.

In some circumstances there could be a state when direct buffers
(instantiated for IO purposes) hold too many memory and to get this
memory back JVM calls System.gc() (as was mentioned earlier by Ivan

ByteBuffer.allocateDirect(capacity)
new DirectButeBuffer(capacity)

Hi, Val! Please take a look to java.nio.Bits.reserveMemory (jdk8). In this
method you can see explicit call of System.gc()

Hi, everyone.
There is a proposal to remove suggestion that user should disable
explicit GC calls in https://issues.apache.org/jira/browse/IGNITE-14720.
Nowadays people usually don't use this facility directly without huge
need (at least we hope so), so this suggestion doesn't bring much
